Answer:
25
Explanation:
In order to solve this the easiest way you can use equivalent fractions.

Since 4 times 5 equals 20 we can multiply 5 times 5 to get our answer.

25 is the answer. But, if we couldn't have gotten to 20 through the multiplication we could use a proportion. That would look like the initial problem but instead of a "?" we would use a variable. I will use <em>t</em> for total.

So now we have our problem set up. The next step is to cross multiply. 4 by <em>t</em> and 5 by 20.

And now we can solve it like a normal algebra problem.

Either way, we get 25.
