REMEMBER: When we convert units of measurement we can use a customary unit study guide. When you're renaming a smaller unit to a larger unit you divide. When you're renaming a larger unit to smaller unit you multiply.

If I ask you to convert 7 feet to inches what would the answer be? Before you begin solving your problem ask yourself this- Am a going large to smaller unit or to a small to larger unit to determine if you're going to multiply or divide.

7 feet = ____ inches

Because feet are larger than inches, I'm going to apply the large to small rule and multiply 7 x 12=

7 feet = 84 inches

Now let's try feet to yards. REMEMBER ask yourself " Am a going large to smaller unit or small to larger unit to determine if you're going to multiply or divide.

9 feet = _____ yards

Because yards are larger than feet I'm going to have to follow the large to small rule and divide 9 feet by 3 yards.

9 feet = 3 yards

because 9 / 3 = 3
