Step-by-step explanation:
just wait i m doing it
let number of boys be 9k
and no. of girls be 5k then
if we add both we shoul get the total number of students
hence 9k + 5k = 448
= 14k = 448
= k = 448/14
= k = 32
hence no of girls = 5k = 5x32 = 160
no of boys = 9k = 9 x32 = 288
all students = 160 + 288 = 448
hence verified.

Answer: 448
Step-by-step explanation:
let number of boys be 9n
and no. of girls be 5k then
if we add both we shoul get the total number of students
hence 9n + 5n = 448
= 14n = 448
= n = 448/14
= n = 32
hence no. of girls = 5n = 5 x 32 = 160
no of boys = 9n = 9 x 32 = 288
all students = 160 + 288 = 448
