Question

$( \frac { 5 } { 7 } + 1 \frac { 6 } { 13 } ) + ( 2 \frac { 5 } { 7 } + 3 \frac { 1 } { 4 } )$
​

Answer 1

Answer:

Given :-

$\longrightarrow$ $\bigg( \dfrac{5} {7} + 1\dfrac{6} {13}\bigg) + \bigg(2 \dfrac{5}{7} + 3 \dfrac{1} {4}\bigg)$

Solution :-

$\longrightarrow$ $\bigg ( \dfrac{5} {7} + 1\dfrac{6} {13}\bigg) + \bigg(2 \dfrac{5} {7} + 3 \dfrac{1} {4}\bigg)$

$\Rightarrow$ $\bigg( \dfrac{5} {7} + \dfrac{19} {13}\bigg) + \bigg(\dfrac{19} {7} + \dfrac{13} {4}\bigg)$

$\Rightarrow$ $\bigg(\dfrac{65 + 133} {91}\bigg)$ + $\bigg(\dfrac{76 + 91} {28}\bigg)$

$\Rightarrow$ $\bigg(\dfrac{198} {91}\bigg)$ + $\bigg(\dfrac{167} {28}\bigg)$

$\Rightarrow$ $\dfrac{198}{91} + \dfrac{167}{28}$

$\Rightarrow$ $\dfrac{792 + 2171}{364}$

$\Rightarrow$ $\dfrac{2963}{364}$

$\Rightarrow$ $8.140$
