2/3 + 3/4. To solve this equation sir you must find a common denominator. The lowest common denominator is 12. It will equal 17/12 or 1 and 5/10.

In order to find this you need to find a common denominator. 2/3 and 3/4 common denominator would be 12 and so what you do to the bottom you must do to the top. 2x4 is 8 and 3x3 is 9. that would make 8/12 and 9/12. 8 plus nine is 17 and 12 stays there so the answer is 17/12 which equals 1 and 5/10.
