Answer 2

➤ Answer :-

$\tt \bigg( \dfrac{2}{5} + \dfrac{2}{7} \bigg) \times \bigg(1 - \dfrac{1}{8} \bigg)$

$\tt \bigg( \dfrac{2}{5} + \dfrac{2}{7} \bigg) \times \bigg( \dfrac{1}{1} - \dfrac{1}{8} \bigg)$

Convert them into like fractions......

LCM of 5 and 7 is 35.

LCM of 1 and 8 is 8.

$\tt \bigg(\dfrac{2 \times 7}{5 \times 7} + \dfrac{2 \times 5}{7 \times 5} \bigg ) \times \bigg( \dfrac{1 \times 8}{1 \times 8} - \dfrac{1}{8} \bigg)$

$\tt \bigg( \dfrac{14}{35} + \dfrac{10}{35} \bigg) \times \bigg( \dfrac{8}{8} - \dfrac{1}{8} \bigg)$

$\: \tt \dfrac{24}{35} \times \dfrac{7}{8} = \dfrac{24 \times 7}{35 \times 8}$

$\: \tt \cancel\dfrac{168}{280} = \dfrac{3}{5}$

$\Huge\therefore$The answer is $\tt\dfrac{3}{5}$
