Answer:

  171/112

Step-by-step explanation:

It can be helpful to write these as mixed numbers.

  45/17 = 2 11/17

  90/19 = 4 14/19

  63/10 = 6 3/10

  171/112 = 1 59/112

  85/18 = 4 13/18

Then the ordering would be ...

  0 < 1 59/112 < 2 11/17 < 4 13/18 < 4 14/19 < 6 3/10

The number closest to zero is 1 59/112 = 171/112.
