# Percentage

Percentage comes from the Latin word "per cent" which means "per hundred".

The symbol used to represent percent is %.

When we say that man gives 30 per cent of his income as income tax, this means that he gives \$30 out of every hundred dollar of his income.

If a student scores 75 marks out of a maximum of 100 in an examination

we say that she has scored 75% marks.

Conversely, if student scored 75% that means he/she got 75 marks out of 100.

Percent can be expressed as fraction and decimal also.

If the student scored 90% is equivalent to 90/100.

Hence, 90% = 90/100

Conversely 90/100 means 90%
