# NCERT 5th Class (CBSE) Mathematics: Percentage

Anisha collects ancient coins. She has collected 100 coins of which 43 coins. We can express this in many ways.

Using fractions we can say 43/100 of her coins are Indian coins.

Using decimals we can say 0.43 coins of her collection are Indian coins. We can also express this as a percentage. The word per cent means ‘per one hundred’. We use the sign % to represent per cent.

43% of Anisha’s coins collection is Indian.

We use percentage very often in our every day lives. Sometimes we use it to compare numbers, sometimes just to understand them. If you see a sale sign that says 20% off it means that for every item that costs Rs. 100 you have to pay Rs. 20 less. If we say that 9% of people were spectacles it means that for every 100 people 9 people were spectacles.

So, 1% means 1 out of 100 or 1/100.

99% means 99 out of 100 or 99/100.

This is a page out of Sunil’s stamp album. The page has 100 stamps. He has stuck them according to their color.
