Final answer:
To divide 18 cans of soda into two groups with a 4 to 5 ratio, you would allocate 8 cans to one group and 10 cans to the other.
Step-by-step explanation:
To divide 18 cans of soda into two groups so that the ratio is 4 to 5, you first need to determine the total number of parts the ratio represents. In this case, the total number of parts is 4 + 5 = 9. To divide the cans, you can calculate 4/9 * 18 = 8 cans for the first group (4 parts out of 9) and 5/9 * 18 = 10 cans for the second group (5 parts out of 9).
