Ta có :
\(\frac{6}{7}=1-\frac{1}{7}\)
\(\frac{7}{8}=1-\frac{1}{8}\)
Vì \(\frac{1}{7}>\frac{1}{8}\) nên \(1-\frac{1}{7}< 1-\frac{1}{8}\)
hay \(\frac{6}{7}< \frac{7}{8}\)

Ta có: \(1-\frac{1}{7}=\frac{6}{7}\)
\(1-\frac{1}{8}=\frac{7}{8}\)
Mà \(\frac{1}{7}>\frac{1}{8}\Rightarrow\frac{6}{7}< \frac{7}{8}\)
