asked • 08/22/19There are 378 students who are enrolled in an introductory biology course. If there are five boys to every two girls, how many boys are in the course?

we know that 5 out of every 7 students are boys, then 5/7 of 378 represent the number of boys.
There are 270 boys, and therefore 108 girls.
the number of girls is 2 out of every 7, or 2/7 of 378, which is 108.
