Question 22778
Well, it would be nice if you had an example, but I'll make some


EXAMPLE
20% of 100
Answer:
Well, that's easy because it is out of 100
so the answer would be 20%

EXAMPLE
50% of 50
answer:
You might already know it is 25, but what if you didn't?
You can do, {{{50*.5}}} or {{{50*1/2}}}
They will both end up as 25


Hope this helps!
