4.) \dfrac {5}{6} +  \dfrac {1}{6} = \dfrac {6}{6} = 1

5.) \dfrac {5}{12} +  \dfrac {11}{12} = \dfrac {16}{12} = 1 \dfrac {4}{12}  = 1 \dfrac {1}{4}

6.) \dfrac {7}{3} +  \dfrac {2}{3} = \dfrac {9}{3} = 3

7.) \dfrac {2}{15} +  \dfrac {5}{15} = \dfrac {7}{15}

8.) \dfrac {2}{9} +  \dfrac {3}{9} + \dfrac {1}{9} = \dfrac {6}{9} = \dfrac {2}{3}

9.) \dfrac {5}{6} +  \dfrac {3}{6} = \dfrac {8}{6} = 2 \dfrac {2}{6} =  2 \dfrac {1}{3}

10.) 4 \dfrac {1}{4} + 2 \dfrac {3}{4} = 6 \dfrac {3}{4}
