# How do you simplify 3/6-2/3?

Jan 12, 2017

$- \frac{1}{6}$
Before subtracting fractions they must have a $\textcolor{b l u e}{\text{common denominator}}$
$\Rightarrow \frac{2}{3} = \frac{2}{3} \times \frac{2}{2} = \frac{4}{6}$
$\Rightarrow \frac{3}{6} - \frac{4}{6} = - \frac{1}{6} \leftarrow \text{ subtracting the numerators}$
