\(\frac{7}{5}+\frac{7}{8}-\frac{1}{8}\times\frac{10}{8}\)
\(=\frac{7\times8+7\times5}{5\times8}-\frac{10}{8}\)
\(=\frac{7\times13}{5\times8}-\frac{50}{40}\)
\(=\frac{91}{40}-\frac{50}{40}=\frac{41}{40}\)
\(\frac{7}{5}+\frac{7}{8}-\frac{1}{8}\times\frac{10}{8}\)
\(=\frac{7}{5}+\frac{7}{8}-\frac{5}{32}\)
\(=\frac{339}{160}\)
\(\frac{7}{5}+\frac{7}{8}-\frac{1}{8}x\frac{10}{8}\)
\(=\frac{7}{5}+\frac{7}{8}-\frac{5}{32}\)
\(=\frac{91}{40}-\frac{5}{32}\)
\(=\frac{167}{80}\)
