1.) Change the mixed numbers to a improper fraction. 2 2/3 changes to 8/3 2 3/5 changes to 13/5
2.) Find the Least Common Factor for the denominator. 3: 3,6,9,12,15 5: 5,10,15 15 will be your Least Common Factor.
3.) Then you would have x/15 + x/15
4.) Multiply the numerator by the number that let you get to 15. Example: The denominator was 3 and 3•5 is 15. The numerator is 8 so you would do 5•8 which is 40. The new fraction would be 40/15.
5.) Do the same with the other improper fraction. Example: 5•3 is 15 so you would do 13•3 which is 39/15
6.) Now you have 40/15+39/15
7.) Add the numerators. Example: 40/15+39/15 40+39=79. You get 79/15
8.) Now that you have an improper fraction you do 79 divided by 15.
9.) 5 4/15 is what you get.
10.) Reduce. In this case you CAN NOT reduce so you are left with 5 4/15
