# How do you solve (6+n)/60=15/90?

Mar 28, 2017

See below.

#### Explanation:

To make the problem easier, let's simplify the denominators first.

$\frac{6 + n}{60} = \frac{15}{90}$

We can multiply both sides by $30$.

$\frac{6 + n}{2} = \frac{15}{3}$

$\frac{15}{3} = 5$

So,
$\frac{6 + n}{2} = 5$ and $6 + n = 10$

Thus,

$n = 4$.

#### Explanation:

$\frac{6 + n}{\text{60}} = \frac{15}{90}$

$$      Eliminate fractions -- multiply the left by 90 and the right by 60.


540 + 90n = 900

$$      Subtract 540 from both sides.


90n = 360

$$      Divide by 90.


n = 4
