Question

Find $\frac{-8}{19}+\frac{2}{57}$

Answer 1

LCM of 19 and 57 is 57.

$\frac{-8}{19}=\frac{-8}{19}\times \frac{3}{3}=\frac{-24}{57}$

$\frac{2}{57}=\frac{2}{57}\times \frac{1}{1}=\frac{2}{57}$

$\frac{-8}{19}+\frac{2}{57}=\frac{-24}{57}+\frac{2}{57}$

$=\frac{-24+2}{57}$

$=\frac{-22}{57}$
