Eureka Math Grade 4 Module 5 Lesson 5 Problem Set Answer Key
Question 1.
Draw horizontal lines to decompose each rectangle into the number of rows as indicated. Use the model to give the shaded area as both a sum of unit fractions and as a multiplication sentence.
a. 2 rows
Answer:
1/4 = 2 x 1/8 = 2/8.
Explanation:
In the above-given question,
given that,
2 rows.
1/4 = 2/8
1/4 = 1/8 + 1/8 = 2/8.
1/4 = 2 x 1/8 = 2/8.
b. 2 rows
Answer:
1/5 = 2 x 1/10 = 2/10.
Explanation:
In the above-given question,
given that,
2 rows.
1/5 = 2/5
1/5 = 1/10 + 1/10 = 2/10.
1/5 = 2 x 1/10 = 2/10.
c. 4 rows
Answer:
1/3 = 4 x 1/6 = 4/6.
Explanation:
In the above-given question,
given that,
2 rows.
1/3 = 2/3
1/3 = 1/6 + 1/6 = 2/6.
1/3 = 4 x 1/6 = 4/6.
Question 2.
Draw area models to show the decompositions represented by the number sentences below. Represent the decomposition as a sum of unit fractions and as a multiplication sentence.
a. \(\frac{1}{2}\) = \(\frac{3}{6}\)
Answer:
1/2 = 1/2 + 1/2 + 1/2.
1/2 = 3/6.
Explanation:
In the above-given question,
given that,
1/2= 3/6
1/2 = 1/2 + 1/2 = 1/2.
1/2 = 3 x 1/2 = 3/6.
b. \(\frac{1}{2}\) = \(\frac{4}{8}\)
Answer:
1/2 = 1/2 + 1/2 + 1/2.
1/2 = 3/6.
Explanation:
In the above-given question,
given that,
1/2= 3/6
1/2 = 1/2 + 1/2 = 1/2.
1/2 = 3 x 1/2 = 3/6.
c. \(\frac{1}{2}\) = \(\frac{5}{10}\)
Answer:
1/2 = 1/4 + 1/2 + 1/2.
1/2 = 3/6.
Explanation:
In the above-given question,
given that,
1/2= 3/6
1/2 = 1/2 + 1/2 = 1/2.
1/2 = 3 x 1/2 = 3/6.
d. \(\frac{1}{3}\) = \(\frac{2}{6}\)
e. \(\frac{1}{3}\) = \(\frac{4}{12}\)
f. \(\frac{1}{4}\) = \(\frac{3}{12}\)
Question 3.
Explain why \(\frac{1}{12}+\frac{1}{12}+\frac{1}{12}\) is the same as \(\frac{1}{4}\).
