Olga decorates blankets with ribbons. She has 12 yards of ribbon. She uses 22 feet of ribbon to decorate blankets. After decorating the blankets, how many feet of ribbons are left?
So first you convert the 12 yards to feet; now you will get 36 feet. If she uses 22 feet, you subtract 22 from 36 to get the answer of 14 feet of ribbon
