(a) Billy has 10/33 of the chocolates.
(b) 33 units = 81 choco == > 1 unit = 81/33 choco
Alice received 8 units = 81/33 X 8 = 19 and 21/33 chocos
Weird......

I believe the question means A has 4/5 of the chocolates of B,C,D total not just B
A will get 36, B will get 18, C will get 18, D will get9

a) Billy has 2/9 of the chocos
b) 81 chocos = 9 units ==> 1 unit = 9 chocos
Alice has 4 units = 4 X 9 = 36 chocos
