[tex]3 \frac{1}{2} + 2 \frac{1}{6} = \frac{7}{2} + \frac{13}{6} = \frac{21}{6} + \frac{13}{6} = \frac{34}{6} = 5 \frac{4}{6} = 5 \frac{2}{3} [/tex]
b)
[tex]2 \frac{2}{3} + 2 \frac{2}{3} = 4 \frac{4}{3} = 5 \frac{1}{3} [/tex]
c)
[tex] \frac{4}{9} + \frac{5}{6} = \frac{8}{18} + \frac{15}{18} = \frac{23}{18} = 1 \frac{5}{18} [/tex]
d)
[tex] \frac{7}{20} + \frac{17}{30} = \frac{21}{60} + \frac{34}{60} = \frac{55}{60} = \frac{11}{12} [/tex]
e)
[tex] \frac{5}{6} + \frac{5}{8} = \frac{20}{24} + \frac{15}{24} = \frac{35}{24} = 1 \frac{11}{24} [/tex]
f)
[tex]1 \frac{1}{4} + 3 \frac{1}{6} = \frac{5}{4} + \frac{19}{6} = \frac{15}{12} + \frac{38}{12} = \frac{53}{12} = 4 \frac{5}{12} [/tex]
g)
[tex]1 \frac{1}{3} + 3 \frac{1}{2} = \frac{4}{3} + \frac{7}{2} = \frac{8}{6} + \frac{21}{6} = \frac{29}{6} = 4 \frac{5}{6} [/tex]
