Answer

0.75 day

Work Step by Step

18 hr = __day Use a unit fraction with min (the unit for your answer) in the numerator, and hr (the unit being changed) in the denominator. Because 24 hr = 1 day, the necessary unit fraction is (1 day)/(24 hr) Multiply 18 hr times the unit fraction. 18hr * (1 day)/(24 hr) = 3/4 day = 0.75 day
