Understanding percentages is a fundamental skill in mathematics and everyday life. Whether you are managing finances, analyzing data, or simply trying to figure out a tip at a restaurant, being able to calculate percentages is incredibly important. In this article, we will delve into the concept of percentages and specifically discuss the question, “15 is what percent of 60?”
What are Percentages?
Percentages are a way of expressing a fraction or a ratio as a portion of 100. The term “percent” literally means “per hundred.” It is denoted by the symbol “%”. For example, when we say “15%”, we are actually saying “15 out of 100” or “15 per 100.”
Calculating Percentages
When it comes to calculating percentages, there are two main methods: using proportions and using the percentage formula.
Method 1: Using Proportions
- Set up a proportion: “15 is to what as 60 is to 100”
- Cross multiply and solve for the missing term
- Convert the result to a percentage by multiplying by 100
Method 2: Using the Percentage Formula
- Identify the given values: the part (15) and the whole (60)
- Substitute the values into the percentage formula: (part/whole) * 100
- Calculate the percentage
15 is What Percent of 60?
Now, let’s specifically address the question at hand: “15 is what percent of 60?” To find the percentage, we will utilize the percentage formula.
The percentage formula: (part/whole) * 100
Substituting the given values, we get:
(15/60) * 100 = 0.25 * 100 = 25%
So, 15 is 25% of 60.
Applications of Percentages
Percentages are widely used in various real-life applications, including:
- Finance: calculating interest rates, discounts, and investments
- Statistics: analyzing data and survey results
- Science: expressing concentrations and proportions
- Everyday life: determining tips, discounts, and tax rates
Importance of Understanding Percentages
Understanding percentages is crucial for making informed decisions and interpreting information accurately. It allows individuals to:
- Make sound financial decisions

The Concept of Percentage Change
Another important concept related to percentages is percentage change. This represents the relative change between two values and is expressed as a percentage.
The percentage change formula is:
Percentage Change = (New Value – Old Value) / Old Value * 100
This formula is often used to calculate changes in prices, quantities, or other measurable quantities over time.
