Answer:
There are 42 green marbles
Step-by-step explanation:
Let the number of green and red marbles be x
Ratio between green and red marbles = 7 : 3
Sum of green and red marbles = 7x + 3x = 10x
Total marbles = 60
10x = 60
x = 60 / 10
x = 6
Green marbles = 7x = 7 × 6 = 42
Red marbles = 3x = 3 × 6 = 18
∴ There are 42 green marbles
