Answer:

1/18

Step-by-step explanation:

When dividing a fraction with another number or fraction you always do the reciprocal of the second number and it turns into multiplication.

so it'll look like this:  [tex]\frac{1}{9} *\frac{1}{2}[/tex]

then you just multiply straight across to get 1/18 because 1*1 is still 1 and 9*2 is 18
