What is Percentages?

Hi Adam

A percentage is just another way to write a fraction when the denominator is 100. So 12% is just another way to write , which you can also write in decimal form as 0.12. Mathematically 12%, and 0.12 are exactly the same.

When using percentages we are usually thinking of a percentage **of** something. If you want to buy a shirt that costs $45.00 and the merchant says she will give you a 12% discount, that's 12% **of** $45.00 which is 0.12 x 45 = 5.40. Hence the discounted price is $45.00 - $5.40 = $39.60.

Cheers,

Penny
