Question

[nguyễn vũ phương thảo]

tinh bang cach thuan tien

3/4x(5/6+7/8):3/7

Answer 1

[vo phi hung]

         \(\frac{3}{4}\times\left(\frac{5}{6}+\frac{7}{8}\right):\frac{3}{7}\)

\(=\frac{3}{4}\times\frac{41}{24}\times\frac{7}{3}\)

\(=\frac{3}{4}\times\frac{7}{3}\times\frac{41}{24}\)

\(=\frac{3\times7}{4\times3}\times\frac{41}{24}\)

\(=\frac{7}{4}\times\frac{41}{24}\)

\(=\frac{287}{96}\)
