# How do you convert to algebraic expression: 9 times a number divided by 5 is 18?

Jul 14, 2018

The algebraic expression is $\frac{9 n}{5} = 18$.

#### Explanation:

First, let's let "a number" be $n$.

Let's split this up:
"9 times a number":
$9 n$

"divided by 5":
$\frac{9 n}{5}$

"is 18":
$\frac{9 n}{5} = 18$

If you want to solve this, you multiply both sides by $5$, then divide both sides by $9$, and you should get $n = 10$.

Hope this helps!
