\(\frac{14}{15}\cdot\frac{15}{16}\cdot\frac{16}{17}:\frac{14}{51}\)
\(=\frac{14}{17}\cdot\frac{51}{14}\)
\(=\frac{51}{17}=3\)
hs mk nha!!!!!!
\(\frac{14}{15}\times\frac{15}{16}\times\frac{16}{17}:\frac{14}{51}\)
\(=\frac{14}{17}:\frac{14}{51}\)
\(=\frac{14}{17}\times\frac{51}{14}\)
\(=\frac{1}{1}\times\frac{3}{1}\)
\(=\frac{3}{1}=3\)
