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


Answer :

(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%
