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%
