given that:- boys : girls= 4:5 it means, there are 4 boys over 5 girls making the whole count 4+5=9
now, number of boys = 4/9 (whole number)
now, number of girls = 5/9 (whole number)
according to the question, if there are total 720 students in school then total number of boys are:-
total number of boys in school = 720 * 4/9= 320
