You first need to have a common denominator
[tex] \frac{2}{3} + \frac{1}{4} =[/tex]
Change the denominators into the nearest common multiple which is 12
[tex] \frac{2}{3} * \frac{4}{4} = \frac{8}{12} [/tex]
[tex] \frac{1}{4} * \frac{3}{3} = \frac{3}{12} [/tex]
[tex] \frac{8}{12} + \frac{3}{12} = \frac{11}{12} [/tex]
[tex] \frac{11}{12} [/tex] is your answer
