Question

Express the following as decimal fractions:

(i)27% (ii)6.3% (iii)32% (iv)0.25% (v)7.5% $\left(vi\right)\frac{1}{8}\%$

Answer 1

$\left(i\right)27\%=\frac{27}{100}=0.27$

$\left(ii\right)6.3\%=\frac{6.3}{100}=\frac{63}{1000}=0.063$

$\left(iii\right)32\%=\frac{32}{100}=0.32$

$\left(iv\right)0.25\%=\frac{0.25}{100}=0.0025$

$\left(v\right)7.5\%=\frac{7.5}{100}=0.075$

$\left(vi\right)\frac{1}{8}\%=\frac{1}{8\times 100}=\frac{1}{800}=\frac{1\times 125}{800\times 125}$

$=\frac{125}{100000}$

=0.00125
