Answer :

2/3.  1/2 is equal to 3/6 and 3/6 + 1/6 is 4/6 and 4/6 simplified is 2/3.
The leat common multiple is 12
multiply your denominator 2×6=12
next multiply the rest
(6×1)+(2×1)/(12)

finally solve
(6+2)/(12)

is (8/12) now we can reduce by dividing both terms by 4

(8÷4)/(12÷4)
gives you (2)/(3) as your answer
