Answer
$\frac{3}{4}$ or 0.75 hr
Work Step by Step
45 min to hours
Put the unit for the answer (hours) in the numerator of the unit fraction; put the unit you want to change (min) in the denominator. As we know 1 hr = 60 min
Unit Fraction equivalent to 1 = (1 hr)/(60 min)
Multiply 45 min times the unit fraction.
45 min * (1 hr)/(60 min) = (45 )/(60 ) = = (3 )/4 hr = 0.75 hr
