$\frac{5}{2}$ ft or 2.5 ft
30 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 $\frac{1 foot}{12 inches}$ Multiply 30 in. times the unit fraction. 30 * $\frac{1 foot}{12 inches}$ = $\frac{5}{2}$ ft = 2.5 ft
