\(\frac{3}{8}\cdot\frac{6}{5}:\frac{1}{5}=\frac{9}{20}:\frac{1}{5}=\frac{9}{4}\)
\(=\frac{3}{8}\cdot\frac{6}{5}\cdot5=\frac{9}{4}\)
\(\frac{3}{8}X\frac{6}{5}:\frac{1}{5}\)
= \(\frac{18}{40}:\frac{1}{5}\)
= \(\frac{7}{4}\)
18/40:1/5 =18/40 nhan 5/1 = 90/40 =9/4
3/8x6/5:1/5
=9/20x5
=\(\frac{9\cdot1}{4\cdot1}=\frac{9}{4}nha\)
