Tính: (⅔ × ⅘) × ¾

\(\left(\frac{2}{3}\times \frac{4}{5}\right)\times \frac{3}{4}\)

\(=\frac{2}{3}\times \left(\frac{4}{5}\times \frac{3}{4}\right)\)

\(=\frac{2}{3}\times \frac{3}{5}=\frac{2}{5}\)

\(\left(\frac{2}{3}\times\frac{4}{5}\right)\times\frac{3}{4}=\frac{2}{3}\times\frac{4}{5}\times\frac{3}{4}=\frac{2}{5}\)
