Question 2. Three dump trucks are carrying topsoil to a construction site. Truck A carries 3,545 lb, Truck B carries 1,758 lb, and Truck C carries 3,697 lb. How many tons of topsoil are the 3 trucks carrying altogether? Answer: The 3 trucks carrying altogether are 4.5 tons. Explanation: Given that there are three dump trucks are carrying topsoil to a construction site and Truck A carries 3,545 lb, Truck B carries 1,758 lb, and Truck C carries 3,697 lb, so the total weight carried altogether is 3,545 + 1,758 + 3,697 = 9,000 lb. As each ton is 2000 pounds, so altogether the trucks are carrying is 9000 × $$\frac{1}{2000}$$ which is 4.5 tons. Question 3. Melissa buys 3$$\frac{3}{4}$$ gallons of iced tea. Denita buys 7 quarts more than Melissa. How much tea do they buy altogether? Express your answer in quarts. Answer: The total tea they bought is 37 quarts. Explanation: Given that Melissa buys 3$$\frac{3}{4}$$ gallons of iced tea, so total iced tea for Melissa is $$\frac{15}{4}$$ which is 3.75. And Denita buys 7 quarts more than Melissa, so the total iced tea for Denita is, as 1 quart is 0.25 gallon and for 7 quarts it will be 7 × 0.25 which is 1.75 gallon. so the total iced tea for Denita is 1.75 + 3.75 which is 5.5. Then the total tea they bought is 3.75 + 5.5 = 9.25 gallon which is 9.25 × 4 = 37 quarts. Question 4. Marvin buys a hose that is 27$$\frac{3}{4}$$ feet long. He already owns a hose at home that is $$\frac{2}{3}$$ the length of the new hose. How many total yards of hose does Marvin have now? Answer: The total yards of hose does Marvin have now is 15 $$\frac{5}{12}$$ yd. Explanation: Given that Marvin buys a hose that is 27$$\frac{3}{4}$$ feet long and he owns a hose at home that is $$\frac{2}{3}$$ the length of the new hose, so $$\frac{2}{3}$$ of 27$$\frac{3}{4}$$ which is $$\frac{2}{3}$$ × $$\frac{111}{4}$$ = $$\frac{222}{12}$$ = 18 $$\frac{1}{2}$$, So the total yards of hose does Marvin have now is 27$$\frac{3}{4}$$ + 18$$\frac{1}{2}$$ = $$\frac{111}{4}$$ + $$\frac{37}{2}$$ = $$\frac{185}{4}$$ = 46 $$\frac{1}{4}$$. So total in yards, it will be 46 $$\frac{1}{4}$$ × 1 yd = $$\frac{185}{4}$$ × $$\frac{1}{3}$$ yd = $$\frac{185}{12}$$ =15 $$\frac{5}{12}$$ yd. ### Eureka Math Grade 5 Module 4 Lesson 20 Exit Ticket Answer Key Convert.

How many minutes did it take them to run the race? Answer: The number of minutes did it take them to run the race is 2 $$\frac{3}{4}$$ mins. Explanation: Given that there are four members of a track team run a relay race in 165 seconds, so the number of minutes did it take them to run the race is 165 × $$\frac{1}{60}$$ = $$\frac{11}{4}$$ = 2 $$\frac{3}{4}$$ mins. Question 3. Horace buys 2$$\frac{3}{4}$$ pounds of blueberries for a pie. He needs 48 ounces of blueberries for the pie. How many more pounds of blueberries does he need to buy? Answer: Horace need more blueberries to buy is 0.25 pounds. Explanation: Given that Horace buys 2$$\frac{3}{4}$$ pounds of blueberries for a pie and he needs 48 ounces of blueberries for the pie, so the number of pounds of blueberries does he need to buy is, as 1 pound is 16 ounces and 1 ton is 2,200 pounds which is 32,000 ounces. As Horace needs 48 ounces of blueberries for the pie and we need to convert into ounce, so Horace need more blueberries to buy is 3 – 2$$\frac{3}{4}$$ which is 3 – $$\frac{11}{4}$$ = $$\frac{1}{4}$$ = 0.25 pounds. Question 4. Tiffany is sending a package that may not exceed 16 pounds. The package contains books that weigh a total of 9$$\frac{3}{8}$$ pounds. The other items to be sent weigh $$\frac{3}{5}$$ the weight of the books. Will Tiffany be able to send the package? Answer: The total package is 15 pounds. Explanation: Given that Tiffany is sending a package that may not exceed 16 pounds and the package contains books that weigh a total of 9$$\frac{3}{8}$$ pounds and the other items to be sent weigh $$\frac{3}{5}$$ the weight of the books. Let the book package be X and let the other package be Y. So from the above problem, X= 9$$\frac{3}{8}$$ which is $$\frac{75}{8}$$ and Y = $$\frac{3}{5}$$ X = $$\frac{3}{5}$$ × $$\frac{75}{8}$$ = $$\frac{225}{40}$$ = 5 $$\frac{5}{8}$$. So the total package is X + Y = 9$$\frac{3}{8}$$ + 5 $$\frac{5}{8}$$ = $$\frac{75}{8}$$ + $$\frac{225}{40}$$ = $$\frac{600}{40}$$ = 15 pounds. ## Eureka Math Grade 5 Module 4 Lesson 2 Answer Key ## Engage NY Eureka Math 5th Grade Module 4 Lesson 2 Answer Key ### Eureka Math Grade 5 Module 4 Lesson 2 Problem Set Answer Key Question 1.

Question 1. Mrs. Onusko made 60 cookies for a bake sale. She sold $$\frac{2}{3}$$ of them and gave $$\frac{3}{4}$$ of the remaining cookies to the students working at the sale. How many cookies did she have left? Answer: The number of cookies left is 5 cookies. Explanation: Given that Mrs. Onusko made 60 cookies for a bake sale and she sold $$\frac{2}{3}$$ of them. So the number of cookies did she sold is $$\frac{2}{3}$$ × 60 which is 40 cookies. So the remaining cookies are 60 – 40 which is 20 cookies. And Mrs. Onusko gave $$\frac{3}{4}$$ of the remaining cookies to the students working at the sale, so $$\frac{3}{4}$$ × 20 which is 15 cookies. So the number of cookies left is 20 – 15 = 5 cookies. Question 2. Joakim is icing 30 cupcakes. He spreads mint icing on $$\frac{1}{5}$$ of the cupcakes and chocolate on $$\frac{1}{2}$$ of the remaining cupcakes. The rest will get vanilla icing. How many cupcakes have vanilla icing? Answer: The remaining vanilla icing is 9 cupcakes. Explanation: Given that Joakim is icing 30 cupcakes and he spreads mint icing on $$\frac{1}{5}$$ of the cupcakes and chocolate, so the number of mint icing is 30 × $$\frac{1}{5}$$ which is 6 cupcakes. And $$\frac{1}{2}$$ of the remaining cupcakes have chocolate icing is 30 × $$\frac{1}{2}$$ which is 15 cupcakes. And the remaining vanilla icing is 30 – (15 + 6) which is 30 – 21 = 9 cupcakes. Question 3. The Booster Club sells 240 cheeseburgers. $$\frac{1}{4}$$ of the cheeseburgers had pickles, $$\frac{1}{2}$$ of the remaining burgers had onions, and the rest had tomato. How many cheeseburgers had tomato? Answer: 90 cheeseburgers had tomato. Explanation: Given that the Booster Club sells 240 cheeseburgers and $$\frac{1}{4}$$ of the cheeseburgers had pickles which means the number of cheese that had pickle is 240 × $$\frac{1}{4}$$ which is 60 burgers. The number of remaining burgers is 240 – 60 which is 180 cheese burgers. And $$\frac{1}{2}$$ of the remaining burgers had onions and rest had tomato which means $$\frac{1}{2}$$ × 180 which is 90. Therefore 90 cheeseburgers had tomato. Question 4. DeSean is sorting his rock collection. $$\frac{2}{3}$$ of the rocks are metamorphic, and $$\frac{3}{4}$$ of the remainder are igneous rocks. If the 3 rocks left over are sedimentary, how many rocks does DeSean have? Answer: The number of rocks that DeSean has are 36. Explanation: Given that DeSean is sorting his rock collection and $$\frac{2}{3}$$ of the rocks are metamorphic, and $$\frac{3}{4}$$ of the remainder are igneous rocks which means $$\frac{1}{3}$$ are igneous rocks, and 3 rocks left over are sedimentary, so the number of rocks that DeSean has are x = $$\frac{2}{3}$$x + $$\frac{3}{4}$$ × $$\frac{1}{3}$$x + 3 which is = $$\frac{8}{12}$$x + $$\frac{3}{12}$$x + 3 = $$\frac{11}{12}$$x + 3 $$\frac{1}{12}$$x = 3 x = 36. So the number of rocks that DeSean has are 36. Question 5. Milan puts $$\frac{1}{4}$$ of her lawn-mowing money in savings and uses $$\frac{1}{2}$$ of the remaining money to pay back her sister. If she has$15 left, how much did she have at first?

The money Milan had at first is $40. Explanation: Given that Milan puts $$\frac{1}{4}$$ of her lawn-mowing money in savings and uses $$\frac{1}{2}$$ of the remaining money to pay back her sister. Let the money that Milan’s has at first be X, the remaining money will be X – $$\frac{1}{4}$$ X = $$\frac{3}{4}$$ X. Now we are going to calculate the money to pay back her sister, which is $$\frac{1}{2}$$ of the remaining money, which is $$\frac{1}{2}$$ × $$\frac{3}{4}$$ X which is $$\frac{3}{8}$$X. So the total money Milan had at first = money for saving + money for paying back + the amount of money left X = $$\frac{1}{4}$$X + $$\frac{3}{8}$$ X + 15 X – $$\frac{1}{4}$$X – $$\frac{3}{8}$$ X = 15 $$\frac{8X – 2X – 3X}{8}$$X = 15 On solving we will get the result as 40. So, the money Milan had at first is$40.

Parks is wearing several rubber bracelets. $$\frac{1}{3}$$ of the bracelets are tie-dye, $$\frac{1}{6}$$ are blue, and $$\frac{1}{3}$$ of the remainder are camouflage. If Parks wears 2 camouflage bracelets, how many bracelets does he have on?

Park has 12 bracelets.

Explanation:
Given that Parks is wearing several rubber bracelets and $$\frac{1}{3}$$ of the bracelets are tie-dye, $$\frac{1}{6}$$ are blue, and $$\frac{1}{3}$$ of the remainder are camouflage and Park wears 2 camouflage bracelets. Let the sum of all braclets be X, and Park wears 2 camouflage bracelets, that is,
$$\frac{1}{3}$$ × (1 – $$\frac{1}{3}$$ – $$\frac{1}{6}$$) × X = 2
$$\frac{1}{3}$$ × ($$\frac{6}{6}$$ – $$\frac{2}{6}$$ – $$\frac{1}{6}$$) × X = 2
$$\frac{1}{3}$$ × $$\frac{3}{6}$$ × X = 2
$$\frac{1}{6}$$ × X = 2
X = 2 ÷ $$\frac{1}{6}$$
X = 2 × 6
= 12.

Question 7.
Ahmed spent $$\frac{1}{3}$$ of his money on a burrito and a water bottle. The burrito cost 2 times as much as the water. The burrito cost $4. How much money does Ahmed have left? Answer: Ahmed have left$12.

Explanation:
Given that Ahmed spent $$\frac{1}{3}$$ of his money on a burrito and a water bottle and the burrito cost 2 times as much as the water, so the water is the burrito cost divided by 2. So water = $$\frac{4}{2}$$ which is $2. And water + burrito is$2 + $4 which is$6. And this $6 is $$\frac{1}{3}$$ of the money and Ahmed have left $$\frac{2}{3}$$ of the money, so$6 ÷ $$\frac{1}{3}$$ = X ÷ $$\frac{2}{3}$$
X = 6 × ($$\frac{2}{3}$$ ÷ $$\frac{1}{3}$$, on solving we will get the result as $12. So the Ahmed have left$12.

Three-quarters of the boats in the marina are white, $$\frac{4}{7}$$ of the remaining boats are blue, and the rest are red. If there are 9 red boats, how many boats are in the marina?

The total number of boats in the marine is 84.

Explanation:
Let the number of boats in the marina be X, and the number of white boats be $$\frac{3}{4}$$X. Then the remaining boats will be X – $$\frac{3}{4}$$X which is $$\frac{X}{4}$$. And now, there are $$\frac{4}{7}$$ of the boats are blue, thus the number of blue boats is $$\frac{4}{7}$$ × $$\frac{X}{4}$$ which is $$\frac{X}{7}$$. And the number of red boats is $$\frac{X}{4}$$ – $$\frac{X}{7}$$ which is $$\frac{3X}{28}$$. And if there are 9 red boats, then $$\frac{3X}{28}$$ = 9 and
3X = 9 × 28 on solving X = 84.
The total number of boats in the marine is 84.

Question 1.
Anthony bought an 8-foot board. He cut off $$\frac{3}{4}$$ of the board to build a shelf and gave $$\frac{1}{3}$$ of the rest to his brother for an art project. How many inches long was the piece Anthony gave to his brother?

Anthony gave his brother 8 inches board.

Explanation:
Given that Anthony bought an 8-foot board, as 1 foot is 12 inches and 8 feet is 8 × 12 which is 96 inches. Anthony cuts $$\frac{3}{4}$$ to build a shelf, so $$\frac{3}{4}$$ × 96 which is 72 inches. So the left board after cutting is 96 – 72 which is 24 inches. And Anthony gave $$\frac{1}{3}$$ of the leftover of his brother which is $$\frac{1}{3}$$ × 24 = 8. So Anthony gave his brother 8 inches board.

Question 2.
Riverside Elementary School is holding a school-wide election to choose a school color. Five-eighths of the votes were for blue, $$\frac{5}{9}$$ of the remaining votes were for green, and the remaining 48 votes were for red.
a. How many votes were for blue?

Explanation:
Given that Five-eighths of the votes were for blue and $$\frac{5}{9}$$ of the remaining votes were for green which means $$\frac{5}{9}$$ × $$\frac{3}{8}$$ which is $$\frac{5}{24}$$. And the number of red is 1 – ($$\frac{5}{8}$$ + $$\frac{5}{24}$$ which is $$\frac{1}{6}$$. So the total amount of people is 48 × 6 which is 288 people.
