Proportional reasoning definition math

Rate, Ratio, and Proportional Reasoning. A rate is a ratio. A ratio is a comparison of two numbers. A ratio can be expressed three ways: Using the fraction bar as in 2/3. Using a colon symbol as in 2:3. Using the word "to" as in 2 to 3. When the denominator of a rate is 1, we call the rate a unit rate. We usually use the key word "per.GRADE 7 MATH: PROPORTIONAL REASONING . UNIT OVERVIEW . This is a 3-4 week unit that focuses on identifying and using unit rates.
