How to Find Percentage from Ratio: A Comprehensive Guide

What is a Ratio?

A ratio is a comparison between two quantities. It can be written in several ways, such as a:b, a/b, or "a to b." For instance, if you have 3 apples and 5 oranges, the ratio of apples to oranges is 3:5.

What is a Percentage?

A percentage is a way of expressing a number as a fraction of 100. The word "percent" means "per hundred." So, 50% means 50 out of 100.

The Simple Formula: Ratio to Percentage

The fundamental formula to convert a ratio to a percentage is straightforward:

Percentage = (Part / Whole) * 100

Let's break down how to apply this formula.

Steps to Convert Ratio to Percentage

1. Identify the Ratio: Determine the ratio you want to convert. For example, let's use the ratio 3:5 (apples to oranges).
2. Find the Whole: Add the parts of the ratio to find the whole. In our example, the whole is 3 + 5 = 8.
3. Express as a Fraction: Convert the part you're interested in as a fraction of the whole. If we want to find the percentage of apples, the fraction is 3/8.
4. Divide: Divide the numerator (part) by the denominator (whole). So, 3 ÷ 8 = 0.375.
5. Multiply by 100: Multiply the result by 100 to express it as a percentage. 0.375 * 100 = 37.5%.
6. Add the Percent Symbol: Don't forget to add the "%" symbol to indicate that it's a percentage.

Therefore, the ratio 3:5 translates to 37.5% being apples.

Examples of Converting Ratios to Percentages

Let's look at a few more examples to solidify your understanding:

1. Example 1: In a class, the ratio of boys to girls is 2:3. What percentage of the class are boys?
   
   • Whole = 2 + 3 = 5
   • Fraction = 2/5
   • Percentage = (2/5) * 100 = 40%
   • Therefore, 40% of the class are boys.
2. Example 2: A recipe calls for a sugar to flour ratio of 1:4. What percentage of the recipe is sugar?
   
   • Whole = 1 + 4 = 5
   • Fraction = 1/5
   • Percentage = (1/5) * 100 = 20%
   • Therefore, 20% of the recipe is sugar.
3. Example 3: During a game, a team had 7 successful shots and 3 missed shots. What was their success rate as a percentage?
   
   • Whole = 7 + 3 = 10
   • Fraction = 7/10
   • Percentage = (7/10) * 100 = 70%
   • Therefore, their success rate is 70%.
