There are 384384 students who are enrolled in an introductory engineering course. if there are five boys to every seven girls, how many boys are in the course?

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.
