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%

1) 40 /100 = 40%
