step 1" change to the same Lcd( the lowerst whole # that 8 and 12 can go into evenly) inside the sofe bracket,we should have 24 here.7/8=21/24,and 1/12=2/24!!!!!!! step 2: add them,i.e. (21/24  + 2/24) = 23/24 step 3.: now you just multiply 23/24 with 1/2, your final answer is 23/48. Remember in fraction,you multiply across.

oh,my god!!!!!!!!!!!!!!I need my glasses, I thought it was a dot  infront of the 1/2. Sorry!!!!!!!!!!!!!
