When we convert a fraction, like 4/5 to a percent, we’re asking “What percentage is 4 of 5 ?” To figure this take the Part (4) divided by the Whole (5) x 100.

Part/Whole x 100 = ___ %

So we divide 4 by 5 and multiply by 100 to convert 4/5 to a percent. When we do that, we find that 4/5 is 80%. That means if you take 4/5 of something you are taking 80%.

Note that the fraction 4/5 is less than one so we should have a percentage less than 100%. This is a helpful way to check your work.
