Question

I have 102 sandwiches my friends ate 5/8 of the chicken sandwiches and 2/3 of tuna sandwiches,how many of each sandwiches did I make

Answer 1

Starting from 102, the minimum number of chicken sandwiches has to be divisible by 8 and 3, i.e. 24, that leaves 78 tunas, etc.

So possible combinations may be
Chicken/Tuna
24 / 78
48 / 54
72 / 30
96 / 6
