Answer: choice B) 120

=============================

Step-by-step explanation:

1 yard = 3 ft, 1 ft = 12 inches

Based on those two facts, 1 yard = 36 inches (since 3*12 = 36).

So 25 yards = 900 inches after you multiply both sides by 25.

Divide this over 22 to get 900/22 = 40.909090909091 which rounds down to 40 (see note below). One ribbon gets us 40 pieces, so 3 of them will get 3*40 = 120 which is the answer

note: Why do we round down and not up even though we're really close to 41? Because Erika doesn't have 41 full pieces. Instead, she has 40 whole pieces plus a fraction that is close to 1, but it's not completely there. So we just ignore that fractional part.

Side note: this is assuming that she does not waste any of the fabric. Also keep in mind that the scissors has its own width (however small), so this will likely add a bit of waste. Each scissor slice produces a thin bit of fabric that can't be used. To make things simple, its ideal to ignore this fact.
