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