Question

EX 2.3 Q4 Which is greater: (i ) 2/7 of 3/4 or 3/5 of 5/8 (ii) 1/2 of 6/7 or 2/ 3 of 3/7.

Answer 1

Answer:

$i) \frac{2}{7} \: of \: \frac{3}{4} = \frac{2}{7} \times \frac{3}{4} = \frac{3}{14} \\ \frac{3}{5} \: of \: \frac{5}{8} = \frac{3}{5} \times \frac{5}{8} = \frac{3}{8} \\ denominator \: of \: \frac{3}{8} \: is \: less \: than \: \frac{3}{14} \: so \: \frac{3}{8} \: is \: greater.$

$ii) \frac{1}{2} \times \frac{6}{7} = \frac{3}{7} \\ \frac{2}{3} \times \frac{3}{7} = \frac{2}{7} \\ the \: denominators \: are \: same \: is \: numerator \: of \: \frac{3}{7} \: is \: bigger \: so \: \frac{3}{7} \: is \: the \: ans.$
