1. Fractions and Percents
Objective:
We will learn to compare quantities by using percents.
Learn to write fractions as percents and percents as fractions.

2. A percent means “out of 100”. It describes a part of a 100
A percent means “out of 100” It describes a part of a % means 60 per hundred (or out of 100) So 100% represents a whole.
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. Examples: Write each fraction as a percent.3 20 2 25 36 50

4. To write the percent as a fraction…
Since percent means “out of 100” to convert a percent to a fraction you have to write the percent over a hundred.
Then you must write the fraction in simplest form.
For example: Write the following percent as a fraction.
40% =
40 = = 2

5. Examples: Write each percent as a fraction in simplest form. 6% 24%
68%
