Answer:
-1/6
Explanation:
multiply 1/2 by 6 to get an even denominator. the equation then becomes
(3/12+6/12)-11/12
Simplify what is in perenthesises to 3/4-11/12
Again simplify the denominator by multiplying by 3
the equation then becomes 9/12-11/12
Divide everything by 2
4.5/6 - 5.5/6
4.5-5.5= -1
12/2 =6
put -1 over the demoninator of 6
