What is the formula for finding the total amount of fabric needed when making multiple items?

Back

To find the total amount of fabric needed, multiply the amount of fabric used for one item by the number of items being made. For example, if each cape requires 2/3 yard of fabric and 5 capes are made, the total fabric needed is (2/3) * 5 = 10/3 yards.

How can you express the total amount of dog food needed for a week if a dog is fed a fraction of a cup each day?

Back

To express the total amount of dog food needed for a week, multiply the daily amount of dog food by 7 (the number of days in a week). For example, if a dog is fed 3/4 cup each day, the total for a week is (3/4) * 7 = 21/4 cups.
