Question

Express each of the following ratios as a percent:

$7:5$

Answer 1

Given: $7:5$.

Now,

$7:5=\frac{7}{5}$

$$\begin{gathered} =\frac{7}{5}\times \frac{100}{100} \\ =\left(\frac{7}{5}\times 100\right)\frac{1}{100} \\ =\left(\frac{7}{5}\times 100\right)\% \\ =\frac{700}{5}\% \\ =140\% \end{gathered}$$

Hence, $7:5=140\%$
