Answer 2

1:2

Explanation:

First, find how many are green

Add up the number of blue and red ones:

10 + 15 = 25

Subtract this from 50

50 - 25 = 25

So, 25 are green.

Since there are 50 marbles in total, the ratio will be 25:50

This can be simplified, since both numbers are divisible by 25.

So, the ratio is 1:2
