Mainly to compare fractions with different denominators.

Also to compare anything to a standard of 100, partly because our dollar is based on 100 cents unlike England which used to have pounds, shillings. and pence and who knows what all that menas.

On the news when the say there is 8% unemployment, that means that 8 of every 100 workers doesn't have a job

99% of politicians are liars means 99 of every 100 politicians are liars.

It is an easy way to say you are comparing things to 100.
