Question

Estimate what part of the figures is coloured and hence find the per cent which is coloured

Answer 1

(i) Here, 1 part out of 4 equal parts are shaded which represents the fraction $\frac{1}{4}$

$\frac{1}{4}= \frac{1}{4}\times100\%$

= $25\%$

(ii) Here, 3 parts out of 5 equal parts are shaded which represents the fraction $\frac{3}{5}$

$\frac{3}{5}=\frac{3}{5}\times100\%$

= $60\%$

(iii) Here, 3 parts out of 8 equal parts are shaded which represents the fraction $\frac{3}{8}$

$\frac{3}{8}=\frac{3}{8}\times100\%$

= $\frac{300}{8}\%$

= $37.5\%$
