**When working with math, it is important to know how to calculate percentages. Percentages can be used in a variety of ways; from helping you figure out what portion of a project to do, to calculating discounts, or to determine financial or population growth.**

To calculate a percentage, you need to divide the part of the total that you are interested in by the total amount, and then multiply by 100. The equation looks like this: Part ÷ Total = Percentage (in decimal form) x 100 = Percentage (in percentage form).

Let’s use an example to make it more clear. Say you are shopping at a store and the item you want is 19.99 and you get a 10% discount. To figure out the cost after the discount, you first need to figure out what 10% of 19.99 is. To do this, you would divide 19.99 by 100 to get 0.1999. Then, you would multiply 0.1999 by 10 to get 1.999. Finally, subtract 1.999 from 19.99 to get 17.991. The cost of the item after the 10% discount is 17.991.

Now, let’s look at a slightly more complicated example involving population growth. Say you have a town with a population of 5,000, and it is increasing in size by 10% each year. To calculate the population for the next year, you first need to figure out what 10% of 5,000 is. To do this, you would divide 5,000 by 100 to get 50. Then multiply 50 by 10 to get 500. Finally, add 500 to the starting population of 5,000 to get the new population of 5,500.

As you can see, learning how to calculate percentages can be a useful tool when dealing with math problems. It doesn’t always have to be complicated either. Just start by dividing the part of the total that you are interested in by the total amount, and then multiply by 100. This can help you save money, figure out populations, and make calculations in a variety of other situations.
