2 by 5 into minus 3 by 7 minus 1 by 14 minus 3 by 7 into 3 by 5 + 7 by 14

Answer 1

Solution :-

$\sf\implies\dfrac{2}{5} \times \dfrac{3}{7} - \dfrac{1}{14} - \dfrac{3}{7} \times \dfrac{3}{5} + \dfrac{7}{14}$

$\sf\implies \dfrac{6}{35} - \dfrac{1}{14} - \dfrac{9}{35} + \dfrac{7}{14}$

$\sf\implies \dfrac{12 - 5 - 18 + 35}{70}$

$\sf\implies\dfrac{24}{70}$

$\sf\implies\dfrac{12}{35}$
