Per cent

We can also represent these fractions by ‘per cent’. Per cent or percentage is a way of expressing

The term ‘per cent’ comes from two Latin words ‘per centum’ which means ‘out of 100’. The
symbol of ‘per cent’ is ‘%’.

Percentage is used in day-to-day life as it makes easier to compare the numbers.
