Add the following rational numbers:
$\frac{3}{-8}\text{ and }\frac{1}{8}$
$\frac{3}{-8}\text{ and }\frac{1}{8}$
✓
Answer
$\frac{3}{-8}\text{ and }\frac{1}{8}$
$=\frac{3\times(-1)}{-8\times(-1)}+\frac{1}{8}$
$=\frac{-3}{8}+\frac{1}{8}$
$=\frac{-3+1}{8}=\frac{-2}{8}$
$\frac{-1}{4}$ (Dividing by 2)
$=\frac{3\times(-1)}{-8\times(-1)}+\frac{1}{8}$
$=\frac{-3}{8}+\frac{1}{8}$
$=\frac{-3+1}{8}=\frac{-2}{8}$
$\frac{-1}{4}$ (Dividing by 2)
