I agree, 3 1/2. To solve this word problem, evaluate which system of equation to use. It is asking how many 1/4 liter serving are IN 7/8 or in other words how many times 1/4 going into 7/8 . In order to figure this out you would divide 7/8 by 1/4. To divide you have to find the reciprocal of 1/4 which is 4/1 or 4. Then you multiply 7/8 by 4 which is 7/2 or 3 1/2. :)
