# How do you solve n/4=8/7?

Sep 2, 2016

multiply to cancel out the denominator

#### Explanation:

you are given that $\frac{n}{4}$= $\frac{8}{7}$
we want to get rid of that divided by 4 on the left side
to undo division, we can multiply
but, because this is algebra, we have to multiply both sides by the same thing
so, multiply both sides by 4
$4 \cdot \left(\frac{n}{4}\right) = 4 \cdot \left(\frac{8}{7}\right)$
cancel the 4s, and you are left with
$n = \frac{32}{7}$
