Question

Paul needs to find 310% of 72. which expression should be used?

Answer 1

You must convert the percentage to decimal notation and then multiply it by 72.

As the name implies, percentage is a something per one-hundred; so to convert any percentage to decimal notation we divide by one-hundred:


`(310)/(100)=3.1`

So the 310% of 72 is:


`(3.1)(72)=223.2`
