Question

Add the following fractions.
$\frac{-7}{9},\frac{-3}{4}$

Answer 1

Given

$\frac{-7}{9},\frac{-3}{4}$

$\Rightarrow \frac{-7}{9}+\frac{-3}{4}$

$\Rightarrow \frac{-7\times 4}{9\times 4}-\frac{3\times 9}{4\times 9}$

$\Rightarrow \frac{-28}{36}-\frac{27}{36}$

$\Rightarrow -\frac{55}{36}$
