First, find the lowest common denominator. What does 8, 3, and 6 go into evenly? Let's take the largest number -- 8. Multiples of 8 are 8, 16, 24, 32 . . .
Which of those numbers can be divided evenly by 8, 3, and 6?

Did you get 24?

Next -- divide 24 by the denominators in each fraction.

24/8 = 3

Multiply your answer by the numerator.

3 * 3 = 9

3/8 = 9/24

1/3 = 8/24

5/6 = 20/24

9/24 + 8/24 + 20/24

Add the numerators

9/24 + 8/24 + 20/24 = 37/24

Divide 37 by 24 to get the lowest term.

37/24 = 1 13/24
