# How do you simplify 1/2 + 4/9?

Jan 22, 2017

You first find a common denominator.

#### Explanation:

I hope you can see that this will be $18$.

$= \frac{1}{2} \times \frac{9}{9} + \frac{4}{9} \times \frac{2}{2}$

(in both cases multiplying by $1$ in disguise)

$= \frac{1 \times 9}{2 \times 9} + \frac{4 \times 2}{9 \times 2} = \frac{9}{18} + \frac{8}{18} = \frac{17}{18}$
