Option C is correct
The ratio of green to red marbles is, 3 : 1
Step-by-step explanation:
As per the statement:
A bag contains 44 marbles, some red and some green.
⇒Total marbles = 44
If there are 11 red marbles.

Green marbles = Total marbles - red marbles.
Substitute the given values we have;

Therefore, the ratio of green to red marbles is, 3 : 1
4-1.175=2.825
There was 2.825 liters left in the tank.
