## Hint 1.

In you combine 2/3 bottle of red paint with 4/5 bottle of yellow you get 22/15 bottle of orange. Let t = the Numer of repetions of 2/3 bottle of red and 4/5 bottle of yellow. Then we would have t = 60 (88 divided by 22/15). From this determine how many red and how many yellow.

## Hint 2.

An alternative. Consider the RATIO of red paint to yellow paint.

2/3 : 4/5 simplifies to 5 : 6

We need 5 red bottle for each 6 yellow and a total of 88.

Either of these approaches could be formalized with some algebra.
