Answer
0.25 ft or $\frac{1}{4}$ ft
Work Step by Step
3 in. = ft
Use a unit fraction with foot (the unit for your answer) in the numerator, and inches (the unit being changed) in the denominator. Because 12 inches (in.) = 1 foot (ft), the necessary unit fraction is
(1 foot)/(12 inches)
Multiply 3 in. times the unit fraction.
3 * (1 ft)/(12 in.) = (1 )/(4 ) ft = 0.25 ft
