Answer:
I’ll try to explain in a simple way.
See there are 150 students in a class and out of which their are 2/5 girls means total no. Of students are divided into 5 parts out of which 2 parts are girls ,so first we find out that how many students are their in one part ,for that
150/5=30
Means in one part of students their are 30 students ,which means their are 60 girls (30 students*2 part) so rest students are boys.
That is 150–60=90
Direct method…
2/5 girls in 150 students means
2/5*150=60
No. Of boys :- 150–60= 90
90 boys in the class.
