There are 12 inches (in.) in 1 foot (ft). Which expression can be used to find the number of inches in 2.5 feet? 2.5 ft x 12 in. / 1 ft

2.5 ft x 1 ft / 12 in.

12 in. x 1 in. / 2.5 ft

12 in. x 2.5 ft / 1 in.

Given:

12 inches in 1 foot

number of inches in 2.5 feet

2.5 feet * 12 inches/1foot = 2.5 * 12 inches = 30 inches

1 foot + 1 foot + 0.5 foot = 2.5 feet

12 inches + 12 inches + 6 inches = 30 inches

12 inches : 1 foot = x : 2.5 feet

12 inches * 2.5 feet = x*1foot
