Answer:
Answer is 12, Proof is the attachment
Explanation:
If we have a ratio of 8:3, then it means that every time Kids increases by 8, the adults increase by 3. So, we can fill out the table and add 8 to the kids every time, and add 3 to the adults every time until we have 32 kids and x amount of adults.
Filling out the table we see that when there are 32 kids, there are 12 adults at a birthday party.
Hope this helped!
