\(8\frac{1}{6}:2\frac{1}{2}\) \(1\frac{3}{10}:5\frac{7}{8}\)
\(=\frac{49}{6}:\frac{5}{2}\) \(=\frac{13}{10}:\frac{47}{8}\)
\(=\frac{49}{15}\) \(=\frac{52}{235}\)
8 \(\frac{1}{6}\): 2 \(\frac{1}{2}\)= \(\frac{49}{6}\) + \(\frac{5}{2}\) = \(\frac{49}{6}\) + \(\frac{15}{6}\)= \(\frac{64}{6}\)= \(\frac{32}{3}\)
1 \(\frac{3}{10}\): 5 \(\frac{7}{8}\)= \(\frac{13}{10}\)+ \(\frac{47}{8}\)= \(\frac{104}{80}\)+ \(\frac{470}{80}\)= \(\frac{574}{80}\)
\(8\frac{1}{6}:2\frac{1}{2}\)\(=\frac{49}{6}:\frac{5}{2}\)
\(=\frac{49}{6}.\frac{2}{5}\)\(=\frac{98}{30}=\frac{49}{15}\)
\(1\frac{3}{10}:5\frac{7}{8}\)\(=\frac{13}{10}:\frac{47}{8}\)
\(=\frac{13}{10}.\frac{8}{47}\)\(=\frac{104}{470}=\frac{52}{235}\)
