Welcome! Today we'll learn how to calculate percentages. A percentage shows how much of something you have out of 100 parts. The basic formula is: Percentage equals Part divided by Whole, times 100. Think of it like slicing a pie into pieces.
Let's work through a step-by-step example. What is 15 out of 60 as a percentage? First, identify the part and whole: Part equals 15, Whole equals 60. Then apply the formula: Percentage equals 15 divided by 60, times 100. Finally, calculate: 15 divided by 60 equals 0.25, times 100 equals 25 percent.
There are two common types of percentage calculations. Type 1: Find what percent X is of Y. Use the formula X divided by Y, times 100. For example, 20 is what percent of 80? Answer: 20 divided by 80, times 100 equals 25 percent. Type 2: Find X percent of Y. Use the formula X divided by 100, times Y. For example, what is 30 percent of 200? Answer: 30 divided by 100, times 200 equals 60.
To summarize what we've learned: Percentage equals Part divided by Whole, times 100. Always identify the part and whole clearly. Practice with real-world examples like test scores and sales data. Percentages help us compare different quantities on a common scale.
