VerifiedAs we can see, $2/5$ is already a reduced fraction. But we can also express it as decimal and percentage.

As decimal, divide. Use calculator if needed.

$\begin{aligned} \frac{2}{5}&=0.4 \end{aligned}$

As percentage, divide to convert to a decimal then multiply to 100%

$\begin{aligned} \frac{2}{5}&=0.4\\ &=0.4\times100\%\\ &=40\% \end{aligned}$

We will convert the given fraction to a percentage.

First, write the given reduced fraction into a decimal point.

$\frac{2}{5} = 0.4$

We will multiply $100$ by $0.4$ to convert the decimal point to a percentage and insert the percent sign to the answer.

$\left( 0.4 \right) \left( 100 \right) = 40\%$
