Work Step by Step
Given, Kevin Durant, an NBA basketball player, is 6 $\frac{3}{4}$ ft tall
To find his height in inches,
Use a unit fraction with inches (the unit for your answer) in the numerator, and foot (the unit being changed) in the denominator. Because 12 inches (in.) = 1 foot (ft.), the necessary unit fraction is
$\frac{12 inches}{1 foot}$
Multiply 6 $\frac{3}{4}$ ft times the unit fraction.
$\frac{27}{4}$ ft * $\frac{12 inches}{1 foot}$ = 81 inches
Kevin Durant is 81 inches tall.
