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

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 :

More examples… = = =

Properties of a proportion? Cross Product Property 2 x 6=12 3 x 4 = 2 x 6
