Question

your shadow is 8 feet and your father's shadow is 9 feet. If you are 5.5 feet, how tall is your father in inches

Answer 1

Set up a proportion:

kid/dad = kid/dad

8/9 = 5.5/dad

Cross multiply to solve proportions:

8*dad = 9*5.5

8*dad = 49.5

dad = 6.1875 feet

They want inches so multiply by 12:

74.25 inches

They want "nearest inch" so:

Dad is 74 inches tall.
