Question

Find the sum:

$\frac{-8}{19}+\frac{(-2)}{57}$

Answer 1

We have

$\frac{-8}{19}+\frac{(-2)}{57}$

$=\frac{-8\times 3}{19\times 3}+\frac{(-2)\times 1}{57\times 1}$ [L.C.M. of 19 and 57 is 57, so make both the denominators 57]

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

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

$=\frac{-26}{57}$
