To convert from a measurement with one part to a measurement with multiple parts, determine the number of larger units that fit within the given measurement and then determine how many of the smaller units are left over.


Conversion Strategy 1: Use Division and then Subtraction

 

Example 2

Convert 91 inches into feet and inches.

There are 12 inches in a foot so divide 91 by 12 to determine the number of feet in 91 inches.

There are 7 full feet in 91 inches. Now, convert 7 feet to inches and subtract from 91 to determine the number of inches left over.

Of the 91 inches, 84 inches make up the 7 feet.

So 91 inches is equivalent to 7 feet 7 inches.


Conversion Strategy 2: Use Division with a Remainder

Example 3

Convert 66 to pounds and ounces

There are 16 ounces in a pound, so divide by 16 and state the remainder.

This means there are 4 whole pounds with 2 ounces left over in 66 ounces, So, 66 oz = 4 lbs 2 oz.
