Text Solution

What is Known?

Fractions and pictures.

What is unknown?

Matching of fractions with shaded part of the picture.


Matching can be done by comparing the fractions with the shaded areas of the pictures.


(i) \(\begin{align} 3 \times \frac{1}{5} = \frac{3}{5} \end{align}\) matches with (c) since, \(\begin{align} 3 \times \frac{1}{5} = \frac{1}{5} + \frac{1}{5} + \frac{1}{5} = \frac{3}{5} \end{align}\)

(ii) \(\begin{align} 2 \times \frac{1}{3} = \frac{2}{3} \end{align}\)  matches with (a) Since \(\begin{align} 2 \times \frac{1}{3} = \frac{1}{3} + \frac{1}{3} = \frac{2}{3} \end{align}\)

(iii) \(\begin{align} 3 \times \frac{3}{4} = 2\frac{1}{4} \end{align}\) matches with (b) Since, \(\begin{align} 3 \times \frac{3}{4} = \frac{3}{4} + \frac{3}{4} + \frac{3}{4} = 2\frac{1}{4} \end{align}\)
