Unit 3 Proportionality: Ratios and Rates

2
Objective Students will show that they are ready to move onto this unit by being able to say the following: I can simplify Fractions! I can write equivalent fractions

3
Are you Ready Before we can start with this unit, we must first review Fractions! Simplifying Fractions Equivalent Fractions

4
**Simplifying Fractions**

Please simplify this fraction: 15 24 How did you go about it?

5
**15 24 List all the factor of both the numerator and denominator**

15 24 List all the factor of both the numerator and denominator , 3, 5, , 2, 3, 4, 6, 8, 12, 24 Circle the GCF (greatest common factor) Divide the numerator and denominator by the GCF 15 3 = = 8

6
Can you do these! Write in simplest form!

7
**Equivalent Fractions Write me an equivalent Fraction: 6 8**

What did you do to find this:

8
6 8 In order to find equivalent fractions multiply the numerator and denominator by the same number. 6 x 2 = 12 8 x 2 = 16 Or you can divide the numerator and denominator by the same number. 6 2 = = 4

9
Can you do them? Write equivalent Fractions:
