حاصل ضربهای زیر را به دست آورید. هرجا امکان دارد پاسخ را ساده کنید.
\(\begin{array}{l}2\frac{2}{3} \times \frac{6}{5} = \\\\\frac{4}{3} \times \frac{7}{8} = \\\\\frac{2}{5} \times \frac{5}{2} = \\\\8 \times \frac{1}{8} = \\\\2\frac{1}{3} \times \frac{5}{{14}} = \\\\\frac{3}{5} \times 5 = \\\\5\frac{1}{3} \times 3\frac{1}{8} = \\\\6\frac{3}{4} \times \frac{8}{{54}} = \end{array}\)
\(\begin{array}{l}2\frac{2}{3} \times \frac{6}{5} = \frac{8}{3} \times \frac{6}{5} = \frac{{48}}{{15}} = \frac{{16}}{5}\\\\\frac{4}{3} \times \frac{7}{8} = \frac{{28}}{{24}} = \frac{7}{6}\\\\\frac{2}{5} \times \frac{5}{2} = \frac{{10}}{{10}} = 1\\\\8 \times \frac{1}{8} = \frac{8}{8} = 1\\\\2\frac{1}{3} \times \frac{5}{{14}} = \frac{7}{3} \times \frac{5}{{14}} = \frac{{35}}{{42}} = \frac{5}{6}\\\\\frac{3}{5} \times 5 = \frac{{15}}{5} = 3\\\\5\frac{1}{3} \times 3\frac{1}{8} = \frac{{16}}{3} \times \frac{{25}}{8} = \frac{2}{3} \times \frac{{25}}{1} = \frac{{50}}{3}\\\\6\frac{3}{4} \times \frac{8}{{54}} = \frac{{27}}{4} \times \frac{8}{{54}} = \frac{3}{1} \times \frac{2}{6} = \frac{6}{6} = 1\end{array}\)
