$\frac{2}{5} = \frac{4}{10} = \frac{40}{100} = 0.40 = 40 %$ $2/5 = 4/10 = 40/100 = 0.40 = 40%$

Explanation:

If a fraction is written with a denominator which is a power of 10 it can be written as a decimal. A fraction with a denominator of 100 is immediately the same as a percentage.

The first 2 decimal places represent hundredths, which can be written as a percent.

$\frac{2}{5} = \frac{4}{10} = \frac{40}{100} = 0.40 = 40 %$ $2/5 = 4/10 = 40/100 = 0.40 = 40%$

This can also be done by $\times 100 %$ $xx 100%$

$\frac{2}{5} \times 100 % \leftarrow$ $2/5 xx 100%" "larr$ use the '100' in the calculation

= $40 % \leftarrow$ $40%" "larr$ write the '%' sign in the answer.
