Understanding Percentages

Before we dive into the question, it’s essential to understand the concept of percentages. A percentage is a way of representing a part of a whole in terms of 100. For example, 50% means 50 parts per hundred, or half of the whole.

Formula for Finding Percentages

The formula for finding out what percent one number is of another number is:

Percent = (15/38) x 100

Percent = 39.47%

Rounding Off Percentages

When expressing percentages, it’s best to round off the answer to a whole number or a decimal place that makes sense to the context of the problem. For example, in this case, we can round off the answer to two decimal places since it’s a percentage.

Using a Calculator to Find Out Percentages

Most scientific and graphing calculators come with a percentage button. To find out what percent of 38 is 15, all you need to do is input the numbers as follows:

Common Mistakes When Finding Percentages
