Answer:
Step-by-step explanation:
Give the ratio of red to green to blue marbles to be 3:5:7
Total ratio = 3+5+7 = 15
Total marbles = 600marbles
Amount of red = ratio of red/total ratio × 600
Amount of red marbles = 3/15 × 600
Amount of red marbles = 3×40 = 120marbles
Amount of green marbles = 5/15×600
Amount of green marbles = 5×40 = 200marbles
Amount of blue marbles = 7/15×600
Amount of blue marbles = 7×40 = 280marbles
