Firstly you have to find the LCD ( least common denominator ) it's just like Lcm don't worry!
11 and 2s Lcm is 22 you have to multiply the denominator to make it the Lcm of 22 and you have to do the same thing for the numerator so 9/11 turns into 18/22 and 1/2 turns into 11/22 now you just do normal subtraction!
18/22-11/22= 7/22 IS THE ANSWER

18/22-11/22= 7/22 IS THE ANSWER
7/22, beacause you find a common denominator of both so 22, then make equivalent fractions 18/22 and 11/22 AND SUBTRACT
