3 out of 4, is the same as what out of 20?

We can always multiply top and bottom of a fraction by the same number. Let's see what 4 has been multiplied by. 4 times 5 is 20, so we are multiplying top and bottom by 5

Multiplying the top by 5 also, we have 3 times 5, or 15. So, 3 out of 4, is the same as 15 out of 20
