In mathematics, a percentage is a number or ratio expressed as a fraction of 100.
It is often denoted using the percentage sign: %.
Sometimes we can also write per cent.
- 10% = 10 per cent = 10/100; 30% = 30 per cent = 30/100; etc.
- Fifty percent of Europeans
Percentages are used:
- to talk about fractions when values are considered to be part of a hundred.
- at the start of a sentence in the extended form (per cent).
