Acc. to ques:- 
1------>1/2 piece 
2---->1/8 piece
 the sum of these pieces=  \frac{1}{2} +2* \frac{1}{8}
                                   = \frac{1}{2} +  \frac{1}{4}=  \frac{3}{4}
           
                           remaining part = 1-3/4
                                                = 1/4
from the ques it is clear that last piece is single soo it is 1/4
