Question:
Express the following as decimal fractions:
(i) 27%
(ii) 6.3%
(iii) 32%
(iv) 0.25%
(v) 7.5%
(vi) $\frac{1}{8} \%$
Solution:
(i) $27 \%=\frac{27}{100}$
$=0.27$
(ii) $6.3 \%=\frac{6.3}{100}$
$=0.063$
(iii) $32 \%=\frac{32}{100}$
$=0.32$
(iv) $0.25 \%=\frac{0.25}{100}$
$=0.0025$
$(\mathrm{v}) 7.5 \%=\frac{7.5}{100}$
$=0.075$
$(\mathrm{vi}) \frac{1}{8} \%=\frac{1}{8} \times \frac{1}{100}$
$=\frac{1}{800}$
$=0.00125$
