To find the percentage of a number, you need to firstly divide the initial number by 100, and then multiply it by the percentage number. In this example 50/100 equals 0.5, then you multiply this by the 20 from the percentage which equals 10. Percentages are probably the most used piece of mathematics that you will use after you leave school behind and the majority of the math you studied there. Even with a calculator, you need to be aware of the basic method before you can actually work out the percentage of something.

Percentages are used frequently throughout daily life, in sales and when giving tips in restaurants. It is unbelievably handy to know exactly how much of a saving you will be securing when dashing around clothing sales, or seeing how much money you can save on a new TV or kitchen appliance. You need to be able to remember the formula behind percentages to know how to enter the information on your calculator.

There are other types of percentages that you can learn to help yourself out in your daily life, such as figuring out what percentage a certain number is of another number. To do this, you need to multiply the first number by 100 and then divide it by the number you're trying to find the first percentage of. An example of this is to imagine that the monthly cost of your home is around £1,400 and your monthly earnings are £3,500, you are taking 40 per cent of your income out on your rent costs.

Finally, if you want to calculate the sale price of an item then you need to use the first method of percentages above and then you must subtract this from the former price of the item.
