right or false?

My thinking:

1)  

  (a)   (i) 9996 ($11424*\frac{7}{8}$)

         (ii) It is then a consequential error, if you have (i) wrong,

              then you would also have (ii) wrong.

              21420 ($11424+9996$)

  (b)   (i) rounded to 50.61% ($\frac{42320}{100}$) is 423.2 and ($\frac{21420}{423\frac{1}{5}}$)

  From here I have to go.
