You can put this solution on YOUR website!
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%2A.5 or 50%2A1%2F2
They will both end up as 25

Hope this helps!
