I. Introduction
Calculating percentages is an important skill to have in everyday life. Whether you’re figuring out a discount on a purchase or determining the tip for a meal, percentages are a part of our daily routine. However, for those who struggle with math, calculating percentages can be a daunting task. In this article, we’ll explore the topic of percentages and provide a beginner’s guide on how to calculate 30% of 500.
II. Learn How to Calculate 30 of 500: A Beginner’s Guide
A percentage is a way of expressing a number as a fraction of 100. For example, 50% is the same as 50/100 or 0.5. To calculate a percentage, you need to know the total number you’re working with and the percentage you want to find.
The formula for calculating percentages is:
Percentage = (Part / Whole) x 100
To calculate 30% of 500, we’ll use the formula above. Here are the steps:
Step 1: Write out the formula – Percentage = (Part / Whole) x 100
Step 2: Substitute the values – Percentage = (30 / 500) x 100
Step 3: Simplify the equation – Percentage = 6
So, 30% of 500 is 150.
To further understand this concept, here’s an example problem:
What is 25% of 200?
Step 1: Write out the formula – Percentage = (Part / Whole) x 100
Step 2: Substitute the values – Percentage = (25 / 200) x 100
Step 3: Simplify the equation – Percentage = 12.5
So, 25% of 200 is 50.
