Answer:400
Step-by-step explanation:
Multiply the total number of students by the ratio given
5/7(560)
 
        
             
        
        
        
First you cancel 7 and 28, and 3 and 9, so that leaves you with 4/3 x 15/17, then you cancel 3 and 15 so you get 4x5/17 which should give you 20/17!
