Introduction
When it comes to calculating percentages, things can get a little tricky for some of us. One common question that many people ask is, “what is 20 of $25?” This may seem like a simple question, but there are several ways to approach it, depending on the context in which it is being asked. In this article, we will explore the different methods of calculating 20% of $25 and provide some examples to help you better understand this concept.
Method 1: Multiplying by the Percentage
One way to calculate 20% of $25 is to multiply the dollar amount by the percentage. In this case, we would multiply $25 by 20%, which is equivalent to 0.20 as a decimal. This calculation would look like this:
$25 x 0.20 = $5
Therefore, 20% of $25 is $5.
Method 2: Dividing by the Inverse Percentage
Another way to calculate 20% of $25 is to divide the dollar amount by the inverse of the percentage. In this case, the inverse of 20% is 80%. To find 80% of $25, we would divide $25 by 0.80, which is equivalent to 80% as a decimal. This calculation would look like this:
$25 ÷ 0.80 = $31.25
Therefore, 80% of $25 is $31.25. To find 20% of $25 using this method, we would need to subtract $31.25 from $25 and then round to the nearest cent. This calculation would look like this:
$25 – $31.25 = -$6.25
Since we cannot have a negative percentage, we must round up to the nearest cent, which would be $0. Therefore, 20% of $25 is $0.
Method 3: Using a Calculator
If you are not comfortable with doing mental math or are unsure which method to use, you can always use a calculator to find 20% of $25. Simply input “20% of 25” into your calculator, and it will provide you with the answer, which should be $5.
Examples
To better understand how to calculate 20% of $25, let’s take a look at some examples: Example 1: Sarah went shopping and found a shirt that was on sale for $25. If the shirt is discounted by 20%, how much will she pay? Using method 1, we can multiply $25 by 20%, which would give us:
$25 x 0.20 = $5
Therefore, Sarah will pay $20 for the shirt. Example 2: John ordered a pizza that costs $25. If he wants to leave a 20% tip for the delivery driver, how much will the total cost be? Using method 1, we can multiply $25 by 20%, which would give us:
$25 x 0.20 = $5
Therefore, John will need to leave a $5 tip, making the total cost of the pizza $30.
Conclusion
Calculating percentages may seem intimidating at first, but with a little bit of practice, it becomes much easier. In this article, we explored the different methods of calculating 20% of $25 and provided some examples to help you better understand this concept. Whether you choose to multiply the dollar amount by the percentage, divide by the inverse percentage, or use a calculator, the important thing is to find a method that works best for you.
