First a common denominator, which is 6x9, or 54. 7/9=42/54 and 1l6 =9/54, and subtracting here, you get 33/54 which can be reduced to 11/18 [ans]

First find the LCM (check the link) between two denominators.
9 = 3*3
6 = 2*3
LCM = 2*3*3 = 18
Now this is your new denominator.
7/9 - 1/6
= (7*2 - 1*3) / 18
= (14 - 3) / 18
= 11 / 18

7/9 - 1/6
the LCD of 9 and 6 is 18
= 7*2/9*2 - 1*3/6*3
= 14/18 - 3/18
= 11/18

7/9 - 1/6
= 14/18 - 3/18
= 11/18
--------------
Reason: To find the difference of two fractions, you need to have a common denominator first, and the least common denominator of 9 and 6 is 18.

9x6=54 so what you want to know is what is 42/54-9/54
42-9=33
33/54=11/18
