Convert the following percentages to fractions and ratios:

(i)25% (ii)2.5% (iii)0.25% (iv)0.3% (v)125%

Answer 1

$\left(i\right)25\%=\frac{25}{100}=\frac{1}{4}$ and 1:4

$\left(ii\right)2.5\%=\frac{25}{10\times 100}=\frac{1}{40}$ and 1 : 40

$\left(iii\right)0.25\%=\frac{25}{100\times 100}=\frac{1}{400}$ and 1 : 400

$\left(iv\right)0.3\%=\frac{3}{10}\times \frac{1}{100}=\frac{3}{1000}$ and 3 : 1000

$\left(v\right)125\%=\frac{125}{100}=\frac{5}{4}$ and 5 : 4
