convert mixed fraction into improper fraction.

calculate the sum of the fraction:

So we solve for each
70% of 100=70
students who didn't buy lunch=100-70=30
some of the 70 left so that the students who bought lunch, are 60% of those who are left
we know that the students who didn't buy lunch didn't change number so therefor

40%=30
20%=15
100%=75
