4 What is a Ratio? A ratio is a comparison of two numbers. Ratios can be written in three different ways: a to b a:b Because a ratio is a fraction, b can not be zero Ratios are expressed in simplest form

5 Now, on to proportions! What is a proportion? A proportion is an equation that equates two ratios The ratio of dogs and cats was 3/2 The ratio of dogs and cats now is 6/4=3/2 So we have a proportion :

6 More examples… = = = = =

7 Properties of a proportion? 2x6=12 3x4 = 12 3x4 = 2x6 Cross Product Property

8 SYNTHESIS OF LEARNING  Write down three things you learned today.  Write down tonight’s homework.  Extra time = Quiet work time
