Answer: 16 boys and 14 girls

Step-by-step explanation:

Boys/Students = 2:5

2:5 is 40%  [40% of the students are boys.  0.40 boys/student (think about that)]

If there are a total of 30 students, then:

(0.40 boys/student)*(40 students) = 16 boys.  

30 students - 16 boys = 14 girls

===

Check:  Is 16 boys and 30 students a 2:5 ratio?:

16 boys/30 students = 2:5  YES
