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 \(\frac{3}{8}\)

\(\frac{3}{8}=\frac{3}{8}\times100\%\)

= \(\frac{300}{8}\%\)

= \(37.5\%\)
