Official Solution:

A beverage is sold in 2-liter bottles. If 1 ounce equals 0.03 liters, how many bottles need to be purchased to obtain at least 140 ounces of the beverage?

A. 1
B. 2
C. 3
D. 4
E. 5

One bottle contains $$\frac{2}{0.03} = \frac{200}{3} = 66 \frac{2}{3}$$ ounces of beverage. To get no less than 140 ounces, we need at least 3 bottles.

You cannot have non-integer number of bottles. Thus the least is 3.

I converted to litres first. Please tell me where i'm going wrong.

1 ounce = 0.03 L
140 ounces = x L

x=7.2 L

since each bottle can store 2L. Hence 7.2L can fill 4 bottles.

I think you might want to re-consider your answer. 140*0.03=4.2 L and not 7.2 L. Thus, the answer is 3 bottles.
