Question

Simplify :
$\frac{-9}{10}+\frac{22}{15}$

Answer 1

Lets simplify, $\frac{-9}{10}+\frac{22}{15}$

LCM of $10,15=30$

$=(\frac{-9}{10}\times \frac{3}{3})+(\frac{22}{15}\times \frac{2}{2})$

$=\frac{(-9\times 3)}{30}+\frac{(22\times 2)}{30}$

$=\frac{-27}{30}+\frac{44}{30}$

$=\frac{-27+44}{30}$

$=\frac{17}{30}$

$\therefore \frac{-9}{10}+\frac{22}{15}=\frac{17}{30}$
