Answer:
a. 20 pieces
b. 20cm each
Explanation:
a. 4*5=20
If he cut one of the ropes into 5 pieces, then you do the same to each of them. So that would be 5+5+5+5, which is 20.
b. 100/5=20cm
Using the question, we can assume that each rope is 1M, or 100cm. so instead of making 1meter split into 5 (which would be written as 1/5M) you instead do 100centimeters split into 5, which is 20cm each.
