How do you find a percentage of a number? (besides )

In order to find a percentage, you divide the sample by the total amount.

For example: Tess has 3 cookies out of the total amount of 9. 3/9 = 33.3%

This is a fun one. 

So let me show you an example, 

say we ask the question, 8 is what percent of 32. We can throw these into an equation that looks lime this. X/100=Y/Z, X in this case is 32 because it is the full 100% and we want to find what percent Y (8) is of it. Basically solving for Z. 

So plugging in the numbers, 

32/100=8/Z cross multiply, 800=32z in this problem we get that 8 is 25% of 32. 

That value makes sense so it must be correct. Let me know if you're still confused.
