bạn có chắc ko vậy ???????????????
\(2\frac{1}{3}=\frac{2\cdot3+1}{3}=\frac{7}{3}\)
\(4\frac{2}{5}=\frac{4\cdot5+2}{5}=\frac{22}{5}\)
\(3\frac{1}{4}=\frac{3\cdot4+1}{4}=\frac{13}{4}\)
\(10\frac{3}{10}=\frac{10\cdot10+3}{10}=\frac{103}{10}\)
\(2\frac{1}{3};4\frac{2}{5};3\frac{1}{4};10\frac{3}{10}\)
\(2\frac{1}{3}=\frac{2}{3}\) \(4\frac{2}{5}=\frac{8}{5}\) \(3\frac{1}{4}=\frac{3}{4}\) \(10\frac{3}{10}=3\)
\(2\frac{1}{3};4\frac{2}{5};3\frac{1}{4};10\frac{3}{10}\)
\(2\frac{1}{3}=\frac{7}{3}\) \(4\frac{2}{5}=\frac{22}{5}\) \(3\frac{1}{4}=\frac{13}{4}\) \(10\frac{3}{10}=\frac{103}{10}\)
