Calculating Percent of a Number
Calculating the percent of a number is an important mathematical skill that can come in handy in many everyday situations. To calculate the percent of a number, we need to take the number that we want to find the percentage of (in this case, 250) and divide it by the percentage amount (in this case, 100). The result is then multiplied by 100 to get our answer. In this example, it would be: 250 / 100 = 2.5 x 100 = 250.
So, in answer to the question “100 is what percent of 250?”, the answer is 40%. This calculation can be used for any two numbers; simply divide one by the other and multiply by 100 to get your answer. For example, if you wanted to know what 20% of 500 was, you would divide 500 by 20 and then multiply by 100: 500 / 20 = 25 x 100 = 2500.
