Knowing how to calculate percentages of a given number is a helpful skill to have. It can come in handy in many areas of life, such as when you’re budgeting, shopping, or calculating interest on a loan. In this article, we’ll look at an example of how to calculate 15% of a certain number, in this case, $37.
Understanding Percentages

Before we jump into the example, it’s important to get a better understanding of the concept of percentages. A percentage is just a number or ratio expressed as a fraction of 100. For example, 15% is the same as 15/100 or 0.15. You can use this ratio to calculate a certain portion of a larger number. In this case, we’ll use it to calculate 15% of $37.
Calculating 15% of $37

To calculate 15% of $37, we need to first convert 15% into a decimal. To do this, we divide 15 by 100 to get 0.15. We then multiply 0.15 by 37, which gives us 5.55. This means that 15% of $37 is $5.55.
Calculating Other Percentages

Once you understand how to calculate percentages of a given number, you can use the same method to calculate other percentages. For example, let’s say you want to calculate 25% of $51. First, you convert 25% into a decimal by dividing 25 by 100, which gives us 0.25. Then, you multiply 0.25 by 51, which gives us 12.75. This means that 25% of $51 is $12.75.
In this article, we looked at how to calculate 15% of a certain number, in this case, $37. We first converted 15% into a decimal by dividing it by 100, then multiplied it by the number we wanted to calculate the percentage of. We also looked at an example of how to calculate 25% of a certain number, in this case, $51. Knowing how to calculate percentages is a useful skill to have, and can come in handy in many situations.
