Question

Erika has three pieces of ribbon. Each peice is 25 yards long.she needs to cut pieces that are 22inches long. What is the greatest number of 22-inch pieces that she can cut from the three pieces of ribbon?

Answer 1

Erika has three pieces of ribbon, each of 25 yards' length.

Then in total she has 3·25=75 yards of ribbon.

Since 1 yd = 36 in, then 75 yd = 75·36=2700 in.

Now she needs to cut pieces that are 22 inches long, thus

$2700:22=122\dfrac{16}{22}$ pieces.

Answer: she can cut from the three pieces of ribbon 122 pieces that are 22 inches long.

Answer 2

1 yard=36".
25 yeards = 25*36" = 900"
3 rolls = 3*900 =  2700"
Each piece must be 22" long, so the number of pieces
= 2700/22 = 122 pieces (2684") with 16" left over.
