More than ninety-three percent of the students in a mathematics class are girls. If there is at least one boy in the class, what is the smallest possible size of the class?

Since  we can only  have integer results......the  number of girls  could be .94 * 50  = 47

 

So....the  number  of  boys  =  50 * . 06  =  3

 

So....the smallest possible class size =   50

After reading your question again    ' More than 93%.....' :

I feel the answer is  20

19 girls would be 95%

1 boy would be 5%

15     With 14 girls and 1 boy, the percentage of girls is 14 / 15 which is 93.33% 

         The problem does not stipulate that the percentage has to be an integer.
