Question 4.
To make a garage for his toy truck, Zeno bends a rectangular piece of cardboard in half. He then bends each half in half again. Which of your fraction strips best matches this story?
a. What fraction of the original cardboard is each part? Draw and label the matching fraction strip below.
b. Zeno bends a different piece of cardboard in thirds. He then bends each third in half again. Which of your fraction strips best matches this story? Draw and label the matching fraction strip in the space below.
Answer a :
Explanation :
Zeno bends the rectangular piece into half that means fraction of the part = 1 ÷ 2
Again the half is bends into half again
So, The fraction of each part = ( 1/2) ( 1/2) = 1 ÷ 4 part
Answer b :
Explanation :
Zeno bends the rectangular piece into thirds means it is divided into 3 equal parts = 1 ÷ 3
Again each third is divided into half
So, The Fraction of each part = (1 ÷ 3 ) × (1 ÷ 2 ) = 1 ÷ 6 part .

Question 3.
Dylan plans to eat 1 fifth of his candy bar. His 4 friends want him to share the rest equally. Show how Dylan and his friends can each get an equal share of the candy bar.
Answer:
Explanation :
Dylans eats 1 fifth of his candy bar = 1 ÷ 5

this 4/5 part is divided into 4 friends that means each friend get 1/5 part .
Question 4.
Nasir baked a pie and cut it in fourths. He then cut each piece in half.
a. What fraction of the original pie does each piece represent?
b. Nasir ate 1 piece of pie on Tuesday and 2 pieces on Wednesday. What fraction of the original pie was not eaten?
Answer a :
1/ 8 part
Explanation :
Nasir cuts the pie into fourths that means each part = 1 Fourths
Then Each part of 1 fourths is divided into halves that means each part = (1 ÷ 4) × ( 1 ÷ 2) = 1÷ 8
Answer b :
5 / 8 part was not eaten
Explanation :
Each part = 1 /8 part that means the pie has been divided into 8 parts .
Number of parts eaten on Tuesday = 1
Number of parts eaten on Wednesday = 2
Total parts eaten = 1 + 2 = 3
Remaining parts = 8 – 3 = 5
Fraction of the original pie was not eaten = 5 / 8
