Ans : = $\frac{9}{2}$
Work Step by Step
3 Hours to 40 minutes.
First Write the ratio and divide the common units:
So, $\frac{3 hours}{40 Minutes}$
Now find the lowest term
$\frac{3 hours}{40 Minutes}$
= $\frac{3 \times 60 minutes}{40 Minutes}$ (As 1 hr = 60 mins)
= $\frac{180 minutes}{40 Minutes}$
= $\frac{180}{40}$ (Common units)
= $\frac{180 \div 20}{40 \div 20}$
= $\frac{9}{2}$
