Q.3 Estimate what part of the figures is coloured and hence find the per cent which is coloured.

(i) Fraction of coloured part = $$\frac{1}{4}$$
$$\therefore$$ Percentage of coloured parts
= $$\frac{1×100}{4×100}$$ = $$\frac{100}{4}$$%= 25%
(ii) Fraction of coloured part = $$\frac{3}{5}$$
$$\therefore$$Percentage of coloured parts
= $$\frac{3×100}{5×100}$$= $$\frac{300}{5}$$ %= 60%
(iii) Fraction of coloured part = $$\frac{3}{8}$$
$$\therefore$$ Percentage of coloured parts
$$\frac{3×100}{8×100}$$=$$\frac{300}{8}$$% = 37.5%
