Explain in sentences how you can add or subtract two fractions with common denominators?

Lemur [1.5K]

If two fractions have the same denominators, then just simply add up the numerators together and keep the denominator.

Examples:

$\frac{4}{10} + \frac{5}{10} = \frac{9}{10}$

$\frac{10}{12} - \frac{2}{12} = \frac{8}{12}$
