When working with ratio tables, look for multiplicative relationships. One kind of relationship you can find is to look for a way to get from one ratio part to another ratio part by multiplying. Here, 6 and 12 are both the bottom part of two ratios. To get from 6 to 12, you can multiply by 2. Apply the same relationship to the top parts of the ratio. What is the number of dogs that is missing?

• 12

• 4

• 8

• 6

Another kind of ratio relationship you can find is to look inside a ratio itself. 2:6 is the top ratio in this table.

To get from 2 to 6, you would multiply by 3. Look at each row and notice that this times 3 relationship continues.
