Question

Find the ratio of $40$ minutes to $1.5$hours.

Answer 1

Finding the ratio:

The ratio is calculated for similar quantities only, we must convert hours to minutes.

$$\begin{gathered} 1.5hr=1.5\times 60\{\because 1hr=60min\} \\ =90.0min \end{gathered}$$

Now, the ratio will be $\frac{40}{90}=\frac{4}{9}$

Thus, the required ratio is $\frac{4}{9}$.
