\(\frac{6}{7}:\frac{1}{2}.\frac{3}{4}-\frac{5}{8}\)
\(=\frac{6}{7}.2.\frac{3}{4}-\frac{5}{8}\)
\(=\frac{6.2.3}{7.4}-\frac{5}{8}\)
\(=\frac{3.2.2.3}{7.4}-\frac{5}{8}\)
\(=\frac{3.̸4.3}{7.̸4}-\frac{5}{8}\)
\(=\frac{9}{7}-\frac{5}{8}\)
\(=\frac{72}{56}-\frac{35}{56}\)
\(=\frac{37}{56}\)
Rất vui vì giúp đc bạn <3
