Giải thích:

\(1\frac{1}{3}\,\, + \,\,\frac{1}{6} = \frac{4}{3} + \frac{1}{6} = \frac{8}{6} + \frac{1}{6} = \frac{9}{6} = \frac{3}{2}\)

\(\frac{{61}}{6}\,\, + \,\,\frac{{11}}{3}\,\,:\,\,\frac{{22}}{5} = \frac{{61}}{6} + \frac{{11}}{3} \times \frac{5}{{22}} = \frac{{61}}{6} + \frac{5}{6} = \frac{{66}}{6} = 11\)

\(\frac{6}{7}\,\, \times \,\,\frac{2}{3}\,\, - \,\,\frac{1}{7} = \frac{4}{7} - \frac{1}{7} = \frac{3}{7}\)

\(\frac{4}{5}\,\, + \,\,2\frac{2}{3}\,\, + \,\,4\frac{1}{3} = \frac{4}{5} + \frac{8}{3} + \frac{{13}}{3} = \frac{{12}}{{15}} + \frac{{40}}{{15}} + \frac{{65}}{{15}} = \frac{{117}}{{15}} = \frac{{39}}{5}\)
