6 Simple Tricks To Calculate 15/20 As Percent

Math can be daunting for many, yet some calculations can be made quite simple with the right techniques. Calculating 15/20 as a percent is one such operation that, at first glance, might seem complex but can be effortlessly solved using various straightforward methods. Let's dive into six simple tricks that will make this calculation as easy as pie.

1. The Fraction to Percent Conversion

The most direct way to convert 15/20 to a percentage is by following these steps:

• Divide the numerator by the denominator: 15 ÷ 20 = 0.75.
• Multiply by 100 to get the percentage: 0.75 × 100 = 75%.

Pro Tip: Whenever you need to convert a fraction to a percentage, remember to first get the decimal form by dividing the top number (numerator) by the bottom number (denominator).

2. Simplify and Multiply by 100

Fractions can often be simplified before conversion to simplify calculations:

• Simplify 15/20 to its lowest terms: 15 and 20 both divide by 5, giving us 3/4.
• Convert 3/4 to a percentage: 0.75 × 100 = 75%.

3. Ratio Method

You can use ratios to quickly determine the percentage:

• Express 15/20 as a ratio: 15:20.
• Simplify this ratio: 15:20 simplifies to 3:4.
• Multiply the part by 25 (since there are four parts in total, and we know that 4 parts = 100%): 3 × 25 = 75%.

4. Use Equivalent Fractions

Converting the fraction to equivalent ones can also help:

• Find an equivalent fraction where the denominator is 100: 15/20 = 75/100.
• Read off the numerator as the percentage: 75%.

5. Visualize with Division

You can visualize the problem with division:

• Imagine a pie chart: Divide it into 20 equal parts.
• Identify 15 parts: The percentage of the pie this represents is 75%.

Pro Tip: Visualizing problems can be particularly helpful for those who struggle with abstract math concepts. 

6. Use a Calculator

For those who prefer a straightforward solution:

• Input the values directly: 15 ÷ 20 = 0.75.
• Multiply by 100: 0.75 × 100 = 75%.
