Erika has three pieces of ribbon each peace is 25 yards long she needs to cut pieces that are 22 inches long what is the greatest number of 22 inch pizza is that she can cut from the three pieces of ribbon

Answers

Answer 1

Answer:

Answer:

120 pieces with a bit left over

Step-by-step explanation:

Recall that 1 yard = 36 inches. Thus, a 22-inch piece of ribbon has length

L = (22 inches) / (36 inches / yd) = 11/18 yd.

We must now find out how many 22-inch, or 11/18-yard, pieces can be cut from each 25-yd piece. Divide 25 yd by (11/18 yd/piece), obtaining:

25 yd 18 pieces

--------- * ----------------- = 40.91 pieces.

1 11 yd

Since we're interested in only whole pieces of length 11/18 yd, this produces 40 pieces with 0.91 piece left over.

Cutting up the three 25-yd pieces will then result in 3(40 pieces), or 120, pieces of length 11/18 yd.
