#### Answer

It would be easier to use hours, as it is smaller unit and using the smaller unit we avoid working with fractions and the calculation will be fast.

#### Work Step by Step

Write the ratio of 4 days to 36 hours as a fraction in lowest terms.
(4 days)/(36 hours)
It would be easier to use hours, as it is smaller unit and using the smaller unit we avoid working with fractions and the calculation will be fast.
Now let’s first convert days into hours. As one day is 24 hours. Multiply numerator by 24.
(4 days)/(36 hours)× (24 hours)/(1 day)= (96 hours)/(36 hours)= (96 ÷12)/(36 ÷12)= $\frac{8}{3}$
