Milk and coffee

Thanks for your help!
During a break, each student in a maths class made a full cup of coffee with milk for himself or herself. After having finished her cup, Kathy calculated that she drank one fifth of the total amount of coffee and one seventh of the total amount of milk used by all students in the class. Assuming that all students had cups of the same capacity, how many students had cups of the same capacity, how many students were in the class? Find all possible anwsers.

Re: Milk and coffee

I don't really understand the first part of the question.
