Question

Add the following rational numbers:
$\frac{3}{-8}$ and $\frac{1}{8}$

Answer 1

To, add rational numbers their denominators should be same, so it will become common and numerators will be added to get answer.

$\therefore \frac{3}{-8}=\frac{(3\times (-1\left)\right)}{-8\times (-1))}=\frac{-3}{8}$ and $\frac{1}{8}$

Now, their denominator is same.

So,

$\frac{-3}{8}+\frac{1}{8}=\frac{-3+1}{8}=\frac{-2}{8}=\frac{-1}{4}$
