Frequently asked questions
What is the quickest way to find a percentage?
Find 10% first by moving the decimal point one place left, then build from it. 30% is three lots of 10%; 5% is half of 10%; 25% is a quarter, which is often faster still.
Do I need a calculator?
No. Every question here is chosen so the arithmetic works by hand - the percentage always divides the number cleanly.
How large do the numbers get?
The Largest number setting caps the number a percentage is taken of, from 50 up to 500. The percentages themselves stay the friendly ones whatever it is set to.
What grade is this?
Sixth grade, and it is used constantly from then on - in ratios, in statistics, and in anything involving money.
