# How do you write the mixed expression p-7/(2p) as a rational expression?

May 30, 2017

$\frac{2 {p}^{2} - 7}{2 p}$

#### Explanation:

To do this, we need to put $p$ inside the other fraction. We can do this like this:

$p = p \cdot \frac{2 p}{2 p} = \frac{2 {p}^{2}}{2 p}$

Now, we can rewrite our expression as:

$p - \frac{7}{2 p} = \frac{2 {p}^{2}}{2 p} - \frac{7}{2 p} = \frac{2 {p}^{2} - 7}{2 p}$
