rewrite the equation as
1/5 (1/2 + 1/3)
We must first solve the stuff inside the parentheses, to do this we must find a common denominator, in this case 6
1/2 becomes 3/6 and 1/3 becomes 2/6 thus (1/2 + 1/3) = (3/6 + 2/6) = (5/6)
Now we can multiple (1/5)(5/6) you can cancel out the 5's and then you are left with you answer
1/6
