Explicación paso a paso:
[tex]a)1 \frac{1}{2} + \frac{3}{4} = \frac{3}{2} + \frac{3}{4} = \frac{6 + 3}{4} = \frac{9}{4} = \\ 2 \frac{1}{4} \\ b) \frac{5}{3} + \frac{1}{6} = \frac{10 + 1}{6} = \frac{11}{6} = 1 \frac{5}{6} \\ c) \frac{7}{5} + \frac{9}{10} = \frac{14 + 9 }{10} = \frac{23}{10} = 2 \frac{3}{10} \\ d) \frac{1}{6} + \frac{1}{6} + \frac{1}{3} = \frac{1 + 1 + 2}{6} = \frac{4}{6}
[tex]e) \frac{3}{2} - \frac{1}{4} = \frac{6 - 1}{4} = \frac{5}{4} = 1 \frac{1}{4} \\ f)3 - \frac{6}{5} = \frac{15 - 6}{5} = \frac{9}{5} = 1 \frac{4}{5} [/tex]
