# How do you simplify (12)/(5y^2) - 2/(5yz)?

Aug 23, 2016

$\frac{12 z - 2 y}{5 {y}^{2} z} = \frac{2 \left(6 z - y\right)}{5 {y}^{2} z}$

#### Explanation:

Adding or subtracting fractions - algebraic and arithmetic -requires a common denominator.

$\frac{12}{5 {y}^{2}} - \frac{2}{5 y z} \text{ } L C D = 5 {y}^{2} z$

12/(5y^2) xx z/z - 2/(5yz) xx y/y"

=$\frac{12 z - 2 y}{5 {y}^{2} z}$

This can also be written as $\frac{2 \left(6 z - y\right)}{5 {y}^{2} z}$
