\(2\frac{4}{5}.3\frac{1}{8}\) \(1\frac{1}{5}:1\frac{4}{5}\)
= \(\frac{14}{5}.\frac{25}{8}\) = \(\frac{6}{5}:\frac{9}{5}\)
= \(\frac{35}{4}\) = \(\frac{2}{3}\)
tk mk nha
\(2\frac{4}{5}\cdot3\frac{1}{8}\)
\(=\frac{14}{5}\cdot\frac{25}{8}\)
\(=\frac{35}{4}\)
\(1\frac{1}{5}:1\frac{4}{5}\)
\(=\frac{6}{5}:\frac{9}{5}\)
\(=\frac{2}{3}\)
\(2\frac{4}{5}\)x \(3\frac{1}{8}\)
\(=\frac{14}{5}\)x \(\frac{25}{8}\)
\(=\frac{14x25}{5x8}\)\(=\frac{35}{4}\)
\(1\frac{1}{5}:1\frac{4}{5}\)
\(=\frac{6}{5}:\frac{9}{5}\)
\(=\frac{6}{5}x\frac{5}{9}=\frac{6}{9}=\frac{2}{3}\)
\(2\frac{4}{5}x3\frac{1}{8}\)
\(=\frac{11}{5}x\frac{25}{8}\)
\(=\frac{35}{4}\)
\(1\frac{1}{5}:1\frac{4}{5}\)
=\(\frac{6}{5}:\frac{9}{5}\)
\(=\frac{2}{3}\)
\(2\frac{4}{5}\times3\frac{1}{8}=\frac{14}{5}\times\frac{9}{8}=\frac{63}{20}\)
\(1\frac{1}{5}:1\frac{4}{5}=\frac{6}{5}:\frac{9}{5}=\frac{6}{5}\times\frac{5}{9}=\frac{6}{9}=\frac{2}{3}\)
