18/16, 1/8x9, - 9/8 group 16/18, 8/9, 1/18x16 - 8/9 group 1/8x1/9- neither

The ones that go in 9/8 group are 18/16 and 1/8 × 9.
The ones that go into 8/9 group are 1/18 × 16, 8/9 and 16/18.

Unfortunately, 1/8 × 1/9 does not fit in any of these groups.So it comes in neither..!

The first answer is correct
