• A ratio is a comparison of two numbers

• A proportion is a statement showing that two ratios (fractions) are equal

• Proportions are a comparison of two or more ratios and that their relationship is multiplicative

• Proportional relationships express how quantities change in relationship to each other

• In a statement with two equal fractions, the cross product is the numerator of the first fraction multiplied by the denominator of the second fraction and the numerator of the second fraction multiplied by the denominator of the first fraction

• A rate is a comparison between two quantities with different units of measure

• Rates and ratios can be used to describe patterns in ratio relationships and can be expressed in many forms (tables, graphs, words, and equations)

• A unit rate is a rate that compares a quantity to one unit

• Ratios and proportions can be utilized to solve for unknowns in real-life scenarios and can also be utilized to make predictions

• A function is a relationship between values of one set of numbers to another set
