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.
