Answer:
1 3/8
Step-by-step explanation:
3 2/3 = 11/3
2 2/3 = 8/3
11/3 / 8/3 = 11/3*3/8 = 11/8 = 1 3/8
 
        
                    
             
        
        
        
Answer:
 0.332
Step-by-step explanation:
given series
1/4, 1/16,1/64.1/256
this is geometric series
where common ratio   r is given by 
nth term/ (n-1)th term 
let the second term is nth term and first term is (n-1)th term
r = 1/16 / (1/4) = 1/4
___________________________________________
sum of series is given by
a (1-r^n)/1-r
where a is first term
n is the number of terms 
r is the common ration
___________________________________________
in the given series
1/4, 1/16,1/64.1/256
a = 1/4 
r = 1/4
n = 4
thus ,
sum = 1/4(1-(1/4)^4)/ (1-1/4)
sum = 1/4(1-(1/256)/(4-1)/4
sum = 1/4((256-1)/256 / 3/4
1/4 in numerator and denominator gets cancelled
sum =( 255/256*3) = 255/768 = 0.332
Thus, sum of series is 0.332.
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:

                = 12 - 3
                = 9

                = -8 - 4
                = -12

                 = -60 + 12
                 = -48

             = -2 + 2
             = 0

               = 17

           = 1
