\(1\frac{1}{5}\): \(1\frac{1}{2}\)= \(\frac{6}{5}\): \(\frac{3}{2}\)= \(\frac{6}{5}\)x \(\frac{2}{3}\)= \(\frac{12}{15}\)= \(\frac{3}{5}\)

11/5:11/2=11/5 x 2/11=22/55=2/5
\(\frac{11}{5}\):\(\frac{11}{2}\)
=\(\frac{11}{5}\).\(\frac{2}{11}\)
=\(\frac{2}{5}\)
@ĐỗPhươngThanh.
\(1\frac{1}{5}\div1\frac{1}{2}=\frac{6}{5}\div\frac{3}{2}=\frac{6}{5}\times\frac{2}{3}=\frac{12}{15}=\frac{4}{5}\)
