Question

What percent of $1\mathrm{hour}$ is $30\mathrm{minutes}$?

Answer 1

Convert the given quantity into a percentage.

Let us consider that $x\%$ of an hour is equal to $30\mathrm{minutes}$

$$\begin{gathered} \therefore x\%\mathrm{of}\mathrm{an}\mathrm{hour}=30\mathrm{minutes} \\ \Rightarrow \frac{x}{100}\times 60=30\left[\because 1\mathrm{hour}=60\mathrm{minutes}\right] \\ \Rightarrow x=30\times \frac{100}{60} \\ \Rightarrow x=\frac{100}{2} \\ \Rightarrow x=50 \end{gathered}$$

Hence, $50\%$ of an hour is equal to $30\mathrm{minutes}$.
