Answer:
80%
Step-by-step explanation:
I'm assuming you meant express 4/5 as a percent and not 4/5%. So simply evaluate 4/5 to get 0.80. Now multiply this value by 100 to get the percentage which gives you 80%
 
        
             
        
        
        
8P4 is a permutation;
P(n,r) ; nPr = n!/(n-r)!
8P4 = 8!/(8-4)! = 40,320 / 4! = 40,320 / 24 = 1,680
The value of 8P4 is 1,680
