1. Chapter 9 Lesson 9-1: Understanding Percents
Objective:
We will learn to compare quantities by using percents.

2. Steps to change a fraction into a percent:
A percent is a ratio that describes a part of a % means 60 per hundred (or out of 100). So 100% represents a whole.
Steps to change a fraction into a percent:
Percent means “out of 100”, so you need to write a fraction with a denominator of 100.
So if you have a fraction, you must think: what number do I need to multiply by to get 100.
For example: 7 × 4 = 28
25× 4 = = 28%
* If a fraction is already over 100, the numerator is the percent, for example: 75 = 75%
100

3. When they ask you to use percents to compare fractions, you have to turn the fractions into percents and then say if they are <,>, or =.
For example: and 3 =
6 × 5 = × 10 = 30
20 × 5 = 100 = 30% × 10 = 100 = 30%
Answer: 30% = 30%
