[tex] \frac{35}{12} + \frac{47}{6} = \frac{35}{12} + \frac{94}{12} = \frac{129}{12} = \: \: \: \: \: \: \: \: \: \: \: \frac{43}{4} = \: \: \: 10 \frac{3}{4} [/tex]
2)
[tex] \frac{55}{8} + \frac{16}{3} + \frac{7}{2} = \frac{165}{24} + \frac{128}{24} + \frac{84}{24} = \frac{377}{24} = 15 \frac{17}{24} [/tex]
3)
[tex]\frac{85}{9} + \frac{173}{36} + \frac{121}{18} = \frac{340}{36} + \frac{173}{36} + \frac{242}{36} = \frac{755}{36} = 20 \frac{35}{36} [/tex]
4)
[tex] \frac{146}{21} - \frac{41}{14} = \frac{292}{42} - \frac{123}{42} = \frac{169}{42} = 4 \frac{1}{42} [/tex]
5)
[tex] \frac{2}{1} - \frac{3}{14} = \frac{28}{14} - \frac{3}{14} = \frac{25}{14} = 1 \frac{11}{14} [/tex]
6)
[tex] \frac{67}{8} - \frac{19}{6} = \frac{201}{24} - \frac{76}{24} = \frac{125}{24} = 5 \frac{5}{24} [/tex]
7)
[tex] \frac{58}{9} - \frac{47}{12} = \frac{232}{36} - \frac{141}{36} = \frac{91}{36} = 2 \frac{19}{36} [/tex]
