How do you find missing values in a ratio table?

Back

To find missing values, use equivalent ratios and cross-multiply to solve for the unknown.

If the ratio of A to B is 2:3, what is the value of B if A is 8?

Back

If A is 8, then B is 12, because 8/2 = 4 and 4 * 3 = 12.

Front

What is the purpose of a ratio table?

Back

The purpose of a ratio table is to organize and simplify the comparison of ratios, making it easier to see relationships and solve problems.

Complete the ratio table: If the ratio of x to y is 1:4, what is y when x is 3?

Back

y is 12, because 3 * 4 = 12.

Front

What does it mean if two ratios are equivalent?

Back

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

Front

How can you check if two ratios are equivalent?

Back

You can check if two ratios are equivalent by cross-multiplying the terms and seeing if the products are equal.

If a ratio table shows 2:5, what is the value of the second term if the first term is 10?

Back

The second term is 25, because 10 * (5/2) = 25.
