Giải thích

a) \[\frac{9}{5} + \frac{1}{{10}} = \frac{{18}}{{10}} + \frac{1}{{10}} = \frac{{19}}{{10}}\] b) \[\frac{7}{{16}} + \frac{1}{8} = \frac{7}{{16}} + \frac{2}{{16}} = \frac{9}{{16}}\]

c) \[\frac{{17}}{{12}} + \frac{3}{2} = \frac{{17}}{{12}} + \frac{{18}}{{12}} = \frac{{35}}{{12}}\] d) \[\frac{5}{3} + \frac{1}{6} = \frac{{10}}{6} + \frac{1}{6} = \frac{{11}}{6}\]

e) \[\frac{3}{4} + \frac{9}{8} = \frac{6}{8} + \frac{9}{8} = \frac{{15}}{8}\] f) \[\frac{5}{6} + \frac{{13}}{{18}} = \frac{{15}}{{18}} + \frac{{13}}{{18}} = \frac{{28}}{{18}} = \frac{{14}}{9}\]

g) \[\frac{7}{9} + \frac{2}{3} = \frac{7}{9} + \frac{6}{9} = \frac{{13}}{9}\] h) \[\frac{{11}}{{20}} + \frac{5}{4} = \frac{{11}}{{20}} + \frac{{25}}{{20}} = \frac{{36}}{{20}} = \frac{9}{5}\]
