Before diving into how to find rate percent, let's quickly recap what a percentage is. A percentage is simply a way of expressing a number as a fraction of 100. The word "percent" means "per hundred."
- Finding what percent of a number is: This involves calculating a portion of a whole (e.g., what is 15% of 200?).
- Determining what percentage one number is of another: Here, you're figuring out how one number relates to another in percentage terms (e.g., 30 is what percent of 150?).
- Calculating percentage increase or decrease: This involves finding the percentage change between two values (e.g., what is the percentage change from 80 to 100?).
The Formula for Finding Rate Percent
The core formula you'll need is:
Percentage = (Part / Whole) × 100
Let's break this down with examples:
Example 1: Finding What Percent a Number Is of Another
Problem: You scored 75 out of 100 on a test. What percentage did you get?
Solution:
- Identify the "part" and the "whole":
- Part: 75 (marks scored)
- Whole: 100 (total marks)
- Apply the formula: (75 / 100) × 100 = 75%
Therefore, you scored 75%.
Example 2: Calculating Percentage Increase
Problem: A product's price increased from $50 to $60. What is the percentage increase?
Solution:
- Find the amount of increase: $60 - $50 = $10
- Identify the "original" and the "increase":
- Part: $10 (amount of increase)
- Whole: $50 (original price)
- Apply the formula: ($10 / $50) × 100 = 20%
Therefore, the price increased by 20%.
Example 3: Calculating Percentage Decrease
Problem: A product's price decreased from $60 to $50. What is the percentage decrease?
Solution:
- Find the amount of decrease: $60 - $50 = $10
- Identify the "original" and the "decrease":
- Part: $10 (amount of decrease)
- Whole: $60 (original price)
- Apply the formula: ($10 / $60) × 100 = 16.67% (approximately)
Therefore, the price decreased by approximately 16.67%.
