Ratio Tables and Graphs

A ratio is a comparison of two quantities that shows the relative size of one quantity to another, often expressed as 'a to b' or a:b.

A ratio table is a table that displays pairs of numbers that form equivalent ratios, helping to visualize the relationship between the quantities.

To find equivalent ratios, multiply or divide both terms of the ratio by the same non-zero number.

A graph of a ratio represents the relationship between two quantities, showing how one quantity changes in relation to another.

A ratio table helps organize and simplify the process of finding equivalent ratios and solving problems involving ratios.

To determine the missing value in a ratio table, use the known ratios to set up a proportion and solve for the unknown.

Ratios can be expressed as fractions, where the first quantity is the numerator and the second quantity is the denominator.

To simplify a ratio, divide both terms by their greatest common factor (GCF).

A unit rate is a ratio that compares a quantity to one unit of another quantity, often expressed as 'per unit'.

To convert a ratio to a unit rate, divide both terms of the ratio by the second term.
