30 students.....14 are boys...that means (30 - 14) = 16 are girls

if 2 boys are dropped......14 - 2 = 12 boys
and 2 girls are added......16 + 2 = 18 girls

fraction of the class that are boys is : 12/30 which reduces to 2/5 <==

14/30 =amount of boys
(14-2)/30
12/30=new amount

16/30 =original amount of girls
(16+2)/30=new amount of girls

12/30=6/15=2/5
2/5 is your answer
