1/2 + 2/3 + 5/6 =
We need a common denominator. The least common multiple (LCM)
of 2, 3, 6 is 6 (smallest number each will divide into)
To get the same number on the bottom of each fraction we need
to multiply the first two fractions by an equivalent of 1 that will
give a 6 on the bottom of each:
(1/2)(3/3) = 2/6
(2/3)(2/2) = 4/6
5/6 no need to change
2/6 + 4/6 + 5/6 = (2+4+5)/6 = 11/6 or 1 5/6
