If the ratio of A to B is 2:3, what is the value of A if B is 15?

Back

A = 10, because (2/3) = (A/15) leads to A = 10.

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

Back

To find a missing value, use equivalent ratios to set up a proportion and solve for the unknown.

Front

What does it mean for two ratios to be equivalent?

Back

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

Front

If a ratio is 4:5, what is the total number of parts?

Back

The total number of parts is 4 + 5 = 9.

Front

How can you use a ratio table to solve problems?

Back

You can use a ratio table to organize information, find missing values, and visualize relationships between quantities.

Front

What is the first step in completing a ratio table?

Back

The first step is to identify the known values and the relationship between the quantities.

If the ratio of C to D is 1:4, what is the value of C if D is 20?

Back

C = 5, because (1/4) = (C/20) leads to C = 5.
