Answer:
620
Step-by-step explanation:
5 / 9 = 775
Total number of kids is 775 * 9 / 5 = 1395
Thus number of boys = 1395-775 = 620
Answer:
let the total number of students be x.
boys= 4/9×x= 4x/9
girls=775
so. 4x/9 + 775= x
4x/9 - x = -775
4x-9x/9= - 775
-5x = -775×9
-6975
x= - 6975/ -5 = 1395
now boys = 4/9× 1395=620 boys.
