Directions: Using the digits 0 to 9 at most one time each, fill in the boxes to create a unit rate with the greatest possible value.

Hint
How will the digits you choose affect whether you can have a single digit numerator in the unit rate?
Answer
The unit rate with the greatest possible value is 9 and can be found multiple ways including 3/1 / 2/6 = 9/1 and 6/2 / 1/3 = 9/1

What about (8/2)/(1/9)=36
That was what I was thinking, but there is a box on the right hand side that must also be a digit from 0 to 9.
