In mathematics, percentages are a way of expressing a number as a fraction of 100. Understanding how to calculate percentages is an essential skill for various applications, from everyday tasks to more complex mathematical problems. In this article, we will explore the concept of percentages and dive into the specific question of what percentage of 40 is 10.
Understanding Percentages
Before we delve into the specific calculation of what percentage of 40 is 10, it’s crucial to have a solid understanding of the concept of percentages. A percentage is a way of expressing a number as a fraction of 100. It is often denoted by the % symbol. For example, if we say that 50% of a group of people prefer coffee, we are expressing that half of the group (50 out of 100) prefers coffee.
To calculate a percentage, you can use the following formula:
Percentage = (Part/Whole) x 100
Now, let’s apply this formula to the specific question of what percentage of 40 is 10.
Calculating What Percentage of 40 is 10
When we want to find out what percentage one number is of another, we can use the percentage formula mentioned earlier. In this case, we want to find the percentage of 10 in relation to 40.
Using the formula:
Percentage = (Part/Whole) x 100
We can plug in the numbers:
Percentage = (10/40) x 100
Percentage = (0.25) x 100
Percentage = 25%
So, the answer to the question “What percentage of 40 is 10?” is 25%. In other words, 10 is 25% of 40.
