Question

Subtract the sum of $\frac{3}{4}$ and $\frac{-5}{7}$from the sum of $\frac{-1}{2}$ and $\frac{-4}{7}$.

Answer 1

Sum of $-\frac{1}{2}\&-\frac{4}{7}$

$\frac{-1}{2}+(-\frac{4}{7})=\frac{-1}{2}-\frac{4}{7}=\frac{-7-8}{14}$

$=-\frac{15}{14}$

Sum of $\frac{3}{4}\&-\frac{5}{7}$

$\frac{3}{4}+(-\frac{5}{7})=\frac{3}{4}-\frac{5}{7}=\frac{21-20}{28}$

$=\frac{1}{28}$

Subtract :- $\frac{-15}{14}-\frac{1}{28}$

$=\frac{-30-1}{28}=\frac{-31}{28}$
