Question

What is $\frac{3}{4}$ of an hour?

Answer 1

Convert a fraction of an hour into minutes:

Now,

$$\begin{gathered} \because 1\mathrm{hour}=60\mathrm{minutes} \\ \therefore \frac{3}{4}\mathrm{hour}=\frac{3}{4}\times 60 \\ \Rightarrow =45\mathrm{minutes} \end{gathered}$$

Hence, $\frac{3}{4}$ of an hour is equal to $45\mathrm{minutes}$.
