The ratios are:
red : green = 2 : 3 = (2×3) : (3×3) = 6 : 9
green : blue = 9 : 4
→ ratio of red : green : blue = 6 : 9 : 4
There are 6 + 9 + 4 = 19 parts
76 marbles ÷ 19 parts = 4 marbles per part
→ red: 6 parts = 6 × 4 marbles per part = 24 red marbles
→ green: 9 parts = 9 × 4 marbles per part = 36 green marbles
→ blue: 4 parts = 4 × 4 marbles per part = 16 blue marbles
To check: red + green + blue = 24 marbles + 36 marbles + 16 marbles = 76 marbles in the bag.
