Giải thích

\(\frac{4}{5}\,\, + \,\,\frac{1}{{10}}\,\, - \,\,\frac{1}{2} = \frac{8}{{10}} + \frac{1}{{10}} - \frac{5}{{10}} = \frac{{8 + 1 - 5}}{{10}} = \frac{4}{{10}}\)

\(\frac{1}{2}\,\, \times \,\,\left( {\frac{2}{3}\,\, - \,\,\frac{1}{6}} \right) = \frac{1}{2} \times \left( {\frac{4}{6} - \frac{1}{6}} \right) = \frac{1}{2} \times \frac{3}{6} = \frac{{1 \times \not 3}}{{2 \times 2 \times \not 3}} = \frac{1}{4}\)

\(\frac{2}{5}\,\,:\,\,\frac{6}{{25}} = \frac{2}{5} \times \frac{{25}}{6} = \frac{{\not 2 \times \not 5 \times 5}}{{\not 5 \times \not 2 \times 3}} = \frac{5}{3}\)

\(\frac{1}{3}\,\, + \,\,\frac{5}{6}\,\, + \,\,\frac{1}{2} = \frac{2}{6} + \frac{5}{6} + \frac{3}{6} = \frac{{10}}{6} = \frac{5}{3}\)

\(\left( {\frac{3}{5}\,\, - \,\,\frac{1}{2}} \right)\,\, \times \,\,4 = \left( {\frac{6}{{10}} - \frac{5}{{10}}} \right) \times 4 = \frac{1}{{10}} \times 4 = \frac{4}{{10}}\)

\(\left( {\frac{{11}}{8}\,\, + \,\,\frac{7}{8}} \right)\,\,:\,\,9 = \frac{{18}}{8} \times \frac{1}{9} = \frac{{\not 9 \times \not 2}}{{4 \times \not 2 \times \not 9}} = \frac{1}{4}\)
