1. Divide to go down

2. Multiply to go up

Example 1:

2 mi = ? ft

Feet are smaller than miles; so multiply!

2 x 5280 = 10,560 ft

Example 2:

5 pt = ? c

Cups are smaller than pints; multiply!

2 x 5 = 10 cups

Example 3:

The elevator in an office building has a weight limit posted of one and a half tons. How many pounds can the elevator safely hold?

1 ton = 2,000 pounds

Pounds are smaller than tons; multiply!

1 ½ x 2,000 = 3,000 pounds

Example 4:

1,000 in = ? ft

Feet are larger than inches; Divide!

1,000 ÷ 12 = 83 1/3 feet

Example 5:

6 qt = ? gal

Gallons are larger than quarts; Divide!

6 ÷ 4 = 1 ½ gallons
