If the ratio of A to B is 4:5, what is the value of B if A is 8?

Back

If A is 8, then B is 10, because the ratio 4:5 means for every 4 units of A, there are 5 units of B.

Front

What is the formula to calculate a missing value in a ratio?

Back

The formula is (known value of one ratio)/(known value of the corresponding ratio) = (missing value)/(corresponding missing value).

In a ratio table, if the first column represents hours and the second column represents miles, what does a ratio of 2:1 indicate?

Back

A ratio of 2:1 indicates that for every 2 hours, 1 mile is covered.

What is the value of C if the ratio of A to C is 1:12 and A is 8?

Back

If A is 8, then C is 96, because 8 multiplied by 12 equals 96.

Front

How can you check if your calculated missing value in a ratio table is correct?

Back

You can check by substituting the calculated value back into the ratio and ensuring that the ratios remain equivalent.

Front

What is the relationship between the values in a ratio table?

Back

The values in a ratio table are proportional, meaning they maintain a consistent ratio regardless of the scale.

Front

If the ratio of B to C is 7:8 and B is 70, what is the value of C?

Back

If B is 70, then C is 80, because the ratio 7:8 means for every 7 units of B, there are 8 units of C.
