Question

\(\frac{7}{5}+\frac{7}{8}-\frac{1}{8}\times\frac{10}{8}\)

tính giá trị biểu thức

Answer 1

\(\frac{7}{5}+\frac{7}{8}-\frac{1}{8}\times\frac{10}{8}\)

\(=\frac{7\times8+7\times5}{5\times8}-\frac{10}{8}\)

\(=\frac{7\times13}{5\times8}-\frac{50}{40}\)

\(=\frac{91}{40}-\frac{50}{40}=\frac{41}{40}\)

Answer 2

\(\frac{7}{5}+\frac{7}{8}-\frac{1}{8}\times\frac{10}{8}\)

\(=\frac{7}{5}+\frac{7}{8}-\frac{5}{32}\)

\(=\frac{339}{160}\)

Answer 3

sorry,mik lộn

Answer 4

\(\frac{7}{5}+\frac{7}{8}-\frac{1}{8}x\frac{10}{8}\)

\(=\frac{7}{5}+\frac{7}{8}-\frac{5}{32}\)

\(=\frac{91}{40}-\frac{5}{32}\)

\(=\frac{167}{80}\)
