FAQ
Can the result be more than 100%?
Yes, if the part is larger than the total you entered. In most percentage of total cases, that means one of the inputs is wrong.
Is this the same as finding X% of Y?
No. Here you already know the part and the total, and you want the percentage. In X% of Y, you already know the percentage and want the amount.
Can I use decimals?
Yes. The same formula works with decimals as long as the part and total use the same unit.
