Answer 1

Solution (1) :

$\frac{x}{21} = \frac{2}{3}$

$x \times 3 = 2 \times 21$

$3x = 42$

$x = \frac{42}{3}$

$x = 14$

$∴ \: the \: proportional \: fractions \: are \ \: :$

$\frac{14}{21} = \frac{2}{3}$

Solution (2) :

$\frac{14}{8} = \frac{x}{20}$

$14 \times 20 = 8 \times x$

$8x = 280$

$x = \frac{280}{8}$

$x = 35$

$∴ \: the \: proportional \: fractions \: are \ \ \: :$

$\frac{14}{21} :: \frac{35}{20}$
