4 1/2 + 3 3/4 = 4 2/4 + 3 3/4 = 7 5/4 = 8 1/4...what he needs for A and B
He used 12 inches of cable...
12 - 8 1/4 = 11 4/4 - 8 1/4 = 3 3/4....length left after A and B are made
he doesn't have enough to make the last one...
5 1/8 - 3 3/4 = 41/8 - 15/4 = 41/8 - 30/8 = 11/8 = 1 3/8....he is short by 1 3/8 inches
        
             
        
        
        
I think you have to subtract 60% and 80% which you get 20%
        
             
        
        
        
(3/5)³
=(3³)/(5³)
=27/125
---------------
As:
3*3*3=27
And:
5*5*5=125
        
                    
             
        
        
        
1 1/3 repeating because you will get the dash over it
