Answer:

Cross multiply the cross that doesn't involve x and divide by the number across x. The answer is 90.

Step-by-step explanation:

Start by creating the question. What are you looking for? Resemble it with 'x': \frac{9:3}{x:30}

First step (cross multiply) :

9x30=270

Second step (Divide with the number that is across 'x') :

270/3= 90

x=90

(x) Balls:90

How to double check:

9:3

90:30

Are they equivalent to eachother?

If yes then you are correct.

Hope this helped! :D
