Ratio Tables, Equivalent Ratios, and Graphs

Front

What is a ratio?

Back

A ratio is a comparison of two quantities, showing how many times one value contains or is contained within the other.

Front

What is an equivalent ratio?

Back

Equivalent ratios are ratios that express the same relationship between two quantities, even if the numbers are different.

How do you find a missing number in a ratio table?

Back

To find a missing number in a ratio table, use the relationship between the known numbers to set up a proportion and solve for the unknown.

Front

What is a ratio table?

Back

A ratio table is a table that displays pairs of numbers that form equivalent ratios.

Front

How can you represent ratios graphically?

Back

Ratios can be represented graphically on a coordinate plane, where one quantity is plotted on the x-axis and the other on the y-axis.

Front

If a ratio is 3:4, what is the equivalent ratio for 6:8?

Back

6:8 is an equivalent ratio to 3:4 because both can be simplified to 3:4.

Front

What does it mean if two ratios are proportional?

Back

Two ratios are proportional if they have the same value when simplified.

Front

How do you calculate the cost of multiple items using a ratio table?

Back

To calculate the cost of multiple items, find the unit cost from the ratio table and multiply it by the number of items.

Front

What is the purpose of a graph in representing ratios?

Back

Graphs help visualize the relationship between two quantities, making it easier to see trends and patterns.

Front

How can you determine the rate of change from a graph?

Back

The rate of change can be determined by finding the slope of the line on the graph, which represents how much one quantity changes in relation to another.
