Question

Convert the given fractional numbers to percents.

a) $\frac{1}{8}$

(b) $\frac{5}{4}$

(c) $\frac{3}{40}$

(d) $\frac{5}{4}$

Answer 1

To convert a fraction into per cents we multiply it with $100$

(a) $\frac{1}{8}$

$\frac{1}{8}\times 100\%=\frac{100}{8}\%=12.5\%$

Therefore, $\frac{1}{8}$ in percentage is $12.5\%$

(b) $\frac{5}{4}$

$\frac{5}{4}\times 100\%=5\times 25\%=125\%$

Therefore, $\frac{5}{4}$ in percentage is written as $125\%$

(c) $\frac{3}{40}$

$\frac{3}{40}\times 100\%=3\times \frac{5}{2}\%=7.5\%$

Therefore, $\frac{3}{40}$ in percentage is written as $7.5\%$

(d) $\frac{5}{4}$

$\frac{2}{7}\times 100\%=\frac{200}{7}\%=28.57\%$

Therefore, $\frac{5}{4}$ in percentage is written as $28.57\%$
