First, you add the two ratio numbers to figure out what to divide your 28 cans of soda by.
3=4=7
Next, you divide this amount into your total amount of cans of soda.
28/7=4.
This means that for each one in the ratio, there is 4 cans. So you multiply both numbers in the ratio by 4.
3*4 = 12
4*4=16
So, your final answer is 12:16, or 12 cans of soda in one group, and 16 cans of soda in the other.
For perimeter you add all of the sides but for area you multiply each side
