Answer:

A

Step-by-step explanation:

The total number of marbles = 70 + 42 + 28

Total = 140

Green:Total = 70 / 140 = 1:2

Orange:Total = 42/140 = 6:20 = 3:10

Purple:Total = 28/140 =4/20   = 2:10

1/2 = 5/10

2/10 = 1/5

Check

5/10 + 3/10 + 2/10 = 1 just as it should

Answer: A

B Green is bigger than 1:5. B is incorrect

C Green is bigger than 1:5. C is incorrect
