If in a middle school class, there are 360 students with a boy-to-girl ratio of 4:5, how many boys and how many girls are in the class?
Every 4+5=9 students are boys. That is 4/9 students are boys. So, 360/9 is 40 and 40*4=160. 160 students are boys. Then 360-160=200. 200 students are girls. ChaCha on!
