Question

Answer 1

✪|| Solution ||✪

a + b = b + a

$\bold{ \frac{ -2}{-3} + \frac{1}{5}}$ $\bold{= \frac{ 1}{5} + \frac{-2}{-3}}$

$\bold{ \frac{ -10 + 3}{-15}}$$\bold{= \frac{ 3 + (-10)}{-15}}$

$\bold{ \frac{ -7}{-15}}$$\bold{= \frac{ -7}{-15}}$

$\bold{ \frac{ \cancel{-}7}{\cancel{-}15}}$$\bold{= \frac{ \cancel{-}7}{\cancel{-}15}}$

$\bold{ \frac{ 7}{15}}$$\bold{= \frac{ 7}{15}}$
