9 5 Minute Check Complete in your notes. 3. You have 40 cards you want to divide into two groups so the ratio is 3:2. How many is in each group? Because we have a 3:2 ratio, there will be 5 sections. One group will have 3 sections and one group will have 2 sections. If there are 40 cards divided into 5 sections, there will be 8 cards in each section. That mean the groups will have 3 x 8: 2 x 8, or 24:16.
