Ratio Tables

A ratio is a comparison of two quantities that shows the relative size of one quantity to another, often expressed as '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 a missing value, use the known ratios to set up a proportion and solve for the unknown.

Two ratios are equivalent if they represent the same relationship between quantities, meaning they simplify to the same fraction.

It means for every 1 unit of the first quantity, there are 2 units of the second quantity.

You can use a ratio table to organize information and find missing values, making it easier to solve problems involving proportional relationships.

The purpose is to simplify the process of finding equivalent ratios and solving problems involving proportions.

$50, because the cost is proportional (4 bags = $10, so 20 bags = 5 times that amount).

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

Check if the second quantity is always double the first quantity for all pairs in the table.
