Write a recursive version of the bubbleUp method. The parameter is the index of an element that needs to be bubbled up. You are allowed to create a private helper method if you decide that the public bubbleUp method does not contain enough parameters for recursion. Do NOT use any loop (for, while etc.) otherwise you will get 0 points.

3.0

Step-by-step explanation:

If the ratio is boys to girls, in fraction form (ratio form) that's

When we set up the ratio using the numbers, we have to keep the boy stuff with the boy stuff on top, and the girl stuff with the girl stuff on bottom.  So the ratio with the given numbers is

Reducing that down to decimal form, since 12 is divisible by 4 evenly, would be 3.0
