Answer:
I dont know Ethier ask a teacher or sum gang
In 1 group there is 5 boys and 7girls
total students in 1 group: 7+5=12 students
now we know that there 12 students in 1 group. thus, we find how many groups of 12 are in 384384 students.
number of groups: 384384÷12=32032 groups
in each group we know we have 5 boys, so,
you multiply 5
32032×5=160160 boys
therefore, there is 160160 boys.
