Question

Which of the drawings (a) to (d) show : 
\((a)\)

\((b)\)

\((c)\)

\((d)\)

(i) 2 × \(\frac{1}{5}\)
(ii) 2 × \(\frac{1}{2}\)
(iii) 3 × \(\frac{2}{3}\)
(iv) 3 × \(\frac{1}{4}\)

Answer 1

(i) 2 × \(\frac{1}{5}\) = represents the addition of 2 figures, each representing 1 shaded part out of 5 equal 2 × \(\frac{1}{5}\) parts. Hence, is represented by (d).
(ii) 2 × \(\frac{1}{2}\) = represents the addition of 2 figures, each representing 1 shaded part out of 2 equal 2 × \(\frac{1}{2}\) parts. Hence, is represented by (b).
(iii) 3 × \(\frac{2}{3}\) = represents the addition of 3 figures, each representing 2 shaded parts out of 3 equal 3 × \(\frac{2}{3}\) parts. Hence, is represented by (a).
(iv) 3 × \(\frac{1}{4}\) = represents the addition of 3 figures, each representing 1 shaded part out of 4 equal 3 × \(\frac{1}{4}\) parts. Hence, is represented by (c).
