Answer 2

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
