# How do you solve for b in ab=c?

May 6, 2018

$b = \frac{c}{a}$

#### Explanation:

$a b = c$

To solve for $b$, we have to make it by itself. To do so, let's divide both sides by $\textcolor{b l u e}{a}$:
$\frac{a b}{\textcolor{b l u e}{a}} = \frac{c}{\textcolor{b l u e}{a}}$

$\frac{\cancel{a} b}{\cancel{\textcolor{b l u e}{a}}} = \frac{c}{a}$

$b = \frac{c}{a}$
