The student to teacher ratio at a high school is 17: 3.if the total number of student and teachers is 740, how many of them must be students

Hi!

17 + 3 = 20

740/20 = 37

37 * 17 = 629

Hope this helps! :)

Lets break it down:

You are given the student to teacher ratio (17:3)

The 17:3 means that for every 17 students, you have 3 teachers.

So if there are a total of 740 teachers and students combined, then how many out of those 740 are students.

Lets do some algebra to make it easier,

17x + 3x = 740

20x = 740

x = 37

Now multiply 17:3 by 37 (for both)

37 * 17 = 629

37 * 3 = 111

Lets check out results, to be correct 629/111 must be equal to 17/3

629/111 = 5.6666 repeat

17/3 = 5.6666 repeat

Therefore, we are correct

Out of the 740 total teachers and students combined, 629 of them are students.
