You need a common denominator for 12 and 3, so you multiply by 4 on top and bottom => 2/3 == 8/12.
From there, 11/12 - 8/12 == (11-8)/12 = 3/12 = 1/4
From there, 11/12 - 8/12 == (11-8)/12 = 3/12 = 1/4
11/12 - 2/3
step 1. 33/36 - 24/36 give them a common denominator.
step 2. 33/36 - 24/36 = 9/36 solve it.
step 3. 9/36 = 1/4 simplify it.
