# How do you solve 1 1/3 = 4x ?

$x = \frac{1}{3}$
$1 \frac{1}{3}$ is the same as $1 + \frac{1}{3} = \frac{3}{3} + \frac{1}{3} = \frac{4}{3}$, so the equation is equivalent to $\frac{4}{3} = 4 x$. Now divide both sides by 4 to get $x = \frac{4}{3} \cdot \frac{1}{4} = \frac{\cancel{4}}{3} \cdot \frac{1}{\cancel{4}} = \frac{1}{3}$
