Lisa is getting balloons for her grandfather's birthday party she wants each balloon string to be 9 feet long at the party store string is sold by yard if Lisa wants to get 50 free balloons how many yards of string will she need
If each balloon is 9 feet long, the conversion to yards would be exactly 3. Multiplying 3 yards of string by the amount of balloons will get you how much she needs, in this case, she would need 150 yards of string.
