Answer: If you have a boquet with 20 items with a ratio of 2:3 (baby breath to roses), then you have 8 red roses to 12 baby breath stems.
NOTE: Please let me know if you have a different scenario to solve.
Explanation:
The ratio is (baby breath) 2:3 (roses)
Red roses are 2x and baby breath is 3x
Solve for a boquet containing 20 stems:
2x+3x= 20
5x=20
x=20/5
x=4
Red roses: 2x = 8 stems
Baby breath: 3x = 12 stems
