Answer:
Step-by-step explanation:
First you have to find a common denominator. I chose 6.
2/3=4/6 11/2=33/6
Then i divided to find out how many more students will get some. 33 divided by 4 is 8 with a remainder of 1. So 9 students will get lemonade but the last student will only get 1/6 of a serving.
