Question

subtract the sum of 2 by 3/7 and -5 by 4/7 from the difference of 4/15 and -2/5​

Answer 1

Subtract the sum of 2 by 3/7 and -5 by 4/7 from the difference of 4/15 and -2/5

Answer :

→ According to the question

= $\Bigg( \bigg(2 + \dfrac{3}{7}\bigg ) - \bigg ( -5 + \dfrac{4}{7}\bigg )\Bigg) - \Bigg( \bigg(\dfrac{4}{15}\bigg ) - \bigg ( - \dfrac{2}{5}\bigg )\Bigg)$

= $\Bigg( \bigg(\dfrac{14 + 3}{7}\bigg ) - \bigg ( \dfrac{-35 + 4}{7}\bigg )\Bigg) - \Bigg( \dfrac{4 - 6}{15}\Bigg)$

= $\Bigg( \dfrac{17}{7} - \dfrac{-31}{7}\Bigg) - \Bigg( \dfrac{-2}{15}\Bigg)$

= $\Bigg( (\dfrac{17+31}{7} - \dfrac{-2}{15}\Bigg)$

= $\Bigg( \dfrac{48}{7} - \dfrac{-2}{15}\Bigg)$

= $\Bigg( \dfrac{720 +14 }{105} \Bigg)$

= $\Bigg( (\dfrac{734 }{105} \Bigg)$
