Question

 we have 17 students to 3 faculty members with a total of 740 how many are faculty and how many are students?

Answer 1

17:3

17x + 3x = 740

20x = 740

x = 37

37 * 17 = 629

37 * 3 = 111

There are 629 students and 111 faculty members.

Answer 2

Hi Renee;

 

17 students

3 faculty members.

 

Total above is 20.

 

17/20=0.85=85%

3/20=0.15=15%

 

740 x 0.85 = 629 students

740 x 0.15 = 111 faculty members

 

Let's check our results...

Does 0.85 + 0.15 = 1-------yes!

Does 629 + 111=740-------yes!
