Introduction
If you have ever been in a situation where you need to calculate a percentage, then you know how important it is to have a good grasp of basic math concepts. One of the most common percentage questions is, “What percentage of X is Y?” In this article, we will focus on answering the question, “What percentage of 38 is 15?”
The Formula
To calculate the percentage of one number in relation to another, you need to use a simple formula. The formula is: Percentage = (Part / Whole) x 100 In this case, the “part” is 15 and the “whole” is 38. So, the formula becomes: Percentage = (15 / 38) x 100
Simplifying the Formula
To simplify the formula, we need to first divide 15 by 38. This gives us: 15 / 38 = 0.3947 We then multiply this number by 100 to convert it to a percentage: 0.3947 x 100 = 39.47%
Understanding the Answer
The answer to the question, “What percentage of 38 is 15?” is 39.47%. This means that 15 is 39.47% of 38. In other words, if you had 38 apples and 15 of them were green, then the percentage of green apples would be 39.47%.
Using the Answer
Knowing the percentage of one number in relation to another can be very useful in many different situations. For example, if you are trying to calculate the discount on a $38 item and the discount is 39.47%, then you can easily calculate the discounted price by multiplying $38 by 0.6053 (100% – 39.47%).
Common Mistakes
One common mistake people make when calculating percentages is forgetting to convert the decimal to a percentage. In this case, the decimal 0.3947 needs to be converted to the percentage 39.47%. Another common mistake is mixing up the “part” and “whole” in the formula. It is important to remember that the “part” is the smaller number and the “whole” is the larger number.
Conclusion
Calculating percentages is an important skill to have in many different fields, from finance to science. Knowing how to calculate the percentage of one number in relation to another can help you make informed decisions and solve problems quickly and efficiently.
