find a common denominator. in this case, 24. 2/3 is equivilent to 16/24, 5/8 is equivilent to 15/24, and 5/24 remains the same. then just add the neumerators! 16+15+5=36, and 36/24, which is 3/2, which is 1 and 1/2.

First you have to find a common deenominator between all the fractions, then you add up the numerators and bring over the denominator. then you simplify if needed.

2/3 =   16/24         (2x8=16, 3x8=24)

5/8 =   15/24         (5x3=15, 8x3=24)

5/24 = 5/24          (5x1=5, 24x1=24)

         = 36/24 = 1  1/2  (add up the numorators then simplify to lowest term, if needed)

just  add all the numerators and then all the denominaters and simplify if needed

You add the dinominaters to each other (3,8,24) then add the numerators (2,5,5) hope this helps smiley

Find a common denomenator and write that down next to it as the bottom number. An example would be 1/3 + 2/8. The denomenators would then be 24 because that is a number both go into. 3•8=24, 8•3=24. So then, the problem would be 8/24 + 3/24, which equals 11/24. I'm a fifth grader and even I know that.
