Answer:

x = 20

Step-by-step explanation:

I would say that there are two ways to solve this.

<u>First way: </u>

You could simply this equation be cross multiplying.

4/9 = x/45 → 180 = 9x

Next, divide 180 by 9.

20 = x → x = 20

<u>Second way: </u>

Considering that fraction bars mean division, you could cancel out x/45 by multiplying both fractions by 45.

4/9 = x/45 → 20 = x → x = 20
