Have you ever come across a question asking you to find out what percent of a number is another number? If yes, then you know how tricky these types of questions can be. In this article, we will discuss how to find out what percent of 38 is 15 in the simplest way possible.
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 = (Part/Whole) x 100
Where Part is the number you want to find the percentage of, and Whole is the total number.
Using the Formula to Find Out What Percent of 38 is 15
Now that we have understood the formula let’s use it to find out what percent of 38 is 15.
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:
15 ÷ 38 x 100 = 39.47%
Common Mistakes When Finding Percentages
One common mistake people make when finding percentages is mixing up the part and the whole. Always remember that the part is the number you want to find a percentage of, and the whole is the total number.
Let’s try another example to solidify our understanding. What percent of 80 is 20?
Percent = (20/80) x 100 = 25%
