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.
