Ratio Tables

Ratio Tables

Objective: To use ratio tables to represent and solve problems involving equivalent ratios.

Ratio Tables

Equivalent ratios express the same relationship between quantities.

1: 2 is equivalent to

2: 4 is equivalent to

4: 8 is equivalent to

8:16 is equivalent to

16:32 is equivalent to

?

Ratio Tables

How can you determine if a ratio is equivalent to another ratio?

Dan made \$320 for 40 hours of work. Make a ratio table to determine how much he made for 6 hours of work.

Step 1 – Draw the table. The number of rows will depend on the number of units. The number of columns should be at least 4. You can add more if needed.
