so 9 1/6 - 3 2/9
You want to reduce 9 and 6 ( 9 1/6)
It now becomes 3 1/2 .
then reduce the 3 and the 9 (3 2/9)
Now it becomes 2/3.

Calculate or Multiply 3 •1 which is obviously 3
and now the equation becomes
3/2 - 2/3= 5/6
but how?
you have to find the numerators.
3x3 =9
2x3=6
2x2=4
3x2=6
Subtract all the numbers
9/6 - 4/6= 5/6
hope this helps!
