EXAMPLE 1 Simplify ratios SOLUTION 64 m : 6 m a. Then divide out the units and simplify. b. 5 ft 20 in. b. To simplify a ratio with unlike units, multiply by a conversion factor. a. Write 64 m : 6 m as 64 m 6 m. = 32 3 =32 : 3 5 ft 20 in. = 60 20 = 3 1 = 5 ft 20 in. 12 in. 1 ft Simplify the ratio. 64 m 6 m

GUIDED PRACTICE for Example 1 SOLUTION Then divide out the units and simplify. 24 3 = 8 1 =8 : 1 Simplify the ratio. 1. 24 yards to 3 yards Write 24 yards : 3 yards as 24 3

GUIDED PRACTICE for Example 1 2. 150 cm : 6 m SOLUTION To simplify a ratio with unlike units, multiply by a conversion factors. = 1 4 = 1 : 4 Simplify the ratio. 150cm 6m = 150 6 1m 100cm
