A percentage is a way in which you can express a fraction (or a part of a whole) in portions of 100.
How to find the percentage of any given number: If you were to go to the grocery store and a sign showed that a product is 25% off, you would need to know what the price is of the product that is being discounted by 25%. Let’s say the product is laundry detergent and it normally sells for $8.00. You now know you need to find out what is 25% of $8.00. To do this you must multiply the amount of $8.00 by the percent “25”.
However if you multiply 8.00 x 25, you would get the answer: “200.00”. That certainly cannot be right.
A percentage needs to be converted to a decimal point when you multiply.
25% = .25 as it is 25 of 100 (i.e., 25/100). So we need to multiply $8.00 x .25 which then equals $2.00. $8.00 - $2.00 = $6.00. You can buy the laundry detergent for $6.00.
