3/10=30/100=30%
7/20=35/100=35%
8/25=32/100=32%
We know that 3/10*20=6 students are eating salads.
We also know that 3/5*20=12 students are eating sandwiches.
Assuming each person only eats one thing, there are 20-12-6=2 students eating lunches other than salads or sandwiches.

This is what you could do
