So if Jane drinks one unit, Alex drinks one and a half units. Or, to turn Alex's share into whole units, if Jane drinks 2 units, Alex drinks three. So you have a total of 5 units - divide 150 by 5...? then turn the 3 portions / 2 portions into actual amounts...?

Reading the questions for the first time,I had the same question - who are these two other friends who finished the bottle.... As for the solution - diagram, as usual, is our friend.Draw Jane's glass as two squares, then Alex' glass will be 3 squares. Here is the ratio from the answer
