Let the total numbers of hamsters =H
The number of white hamsters       =5/6H
H - 5/6H =1/6H - the remaining hamsters
1/6H x 8/9 =4/27H are black hamsters
H - [5/6H + 4/27H] =1/54H - yellow hamsters
H =54 hamsters
5/6 x 54 = 45 are white hamsters
[54 - 45] * 8/9 =8 are black hamsters
9 - 8 = 1 is a yellow hamster.

Yellow hamsters =1 / 54
