I'm pretty sure it goes something like:

3/5 = 3➗5 (sorry if that's a box, it's supposed to be a division sign) = 0.6

50*0.6= 30 5th grade students

________________________________________

Another way to think about it is if the denominator is the same as the total, or simplified (if it is simplified, see how many times it goes into the total) just multiply/divide the total by the denominator and the numerator. Here is what I mean:

3/5 = 30/50

Total= 50 Students; Denominator= 50

They are the same, so the numerator stays the same, and also since they are the same, the numerator is also the answer.

OR

3/5

5 goes into 50, 10 times.

3/5 * 10/10 = 30/50

Your answer is the numerator.
