The Basics of Percentages and Calculations
Introduction
When it comes to calculating percentages, it can often be confusing and overwhelming. Even figuring out something as simple as “what is 20 of $15?” might seem like a daunting task. However, with a basic understanding of percentages and a few simple calculations, you can easily find the answer.
What are Percentages?
Percentages are a way of expressing a portion of something as a fraction of 100. For example, if you have 20 out of 100, that is the same as 20%. Similarly, if you have 50 out of 100, that is the same as 50%.
Calculating Percentages
Calculating percentages involves using a simple formula. To find the percentage of something, you need to divide the part by the whole and then multiply by 100. For example, if you have 20 out of 100, you would divide 20 by 100 and then multiply by 100 to get 20%.
What is 20 of $15?
Now that we understand percentages and how to calculate them, we can easily answer the question, “what is 20 of $15?” To do this, we need to first determine what the whole amount is. In this case, the whole amount is $15. We then need to find 20% of $15.
Finding 20% of $15
To find 20% of $15, we need to divide $15 by 100 and then multiply by 20. This gives us: $15 / 100 = $0.15 $0.15 x 20 = $3 So, 20% of $15 is $3.
The Answer
Now that we know that 20% of $15 is $3, we can easily find out what 20 of $15 is. To do this, we simply multiply $3 by 20. This gives us: $3 x 20 = $60 So, 20 of $15 is $60.
