There are 18 girls in Mr. Brimley's math class. If 40% of the students are girls, what is the be
for the number of boys in the class?
А 20
B 30
C 40
D 50
40%=18 girls which leaves 60% boys, 18/40%=18(5/2)=90/2=45. So there are 45 kids in the class. subtract the 18 girls and you get 27 boys so thirty is closest.
