Answer 2

\(\frac{5}{12}-\frac{7}{12}:\frac{14}{11}\)

\(=\frac{5}{12}-\frac{7.11}{12.14}\)

\(=\frac{5}{12}-\frac{11}{24}\)

\(=\frac{10}{24}-\frac{11}{24}\)

\(=\frac{-1}{24}\)

Answer 3

\(\frac{5}{12}-\frac{7}{12}:\frac{14}{11}\)

\(\frac{5}{12}-\frac{7}{12}.\frac{11}{14}\)

\(\frac{5}{12}-\frac{11}{24}\)

\(\frac{10}{24}-\frac{11}{24}\)

\(-\frac{1}{24}\)

Answer 4

\(\frac{5}{12}-\frac{7}{12}\div\frac{14}{11}\)

\(=\frac{5}{12}-\frac{7\times11}{12\times14}\)

\(=\frac{5}{12}-\frac{11}{24}\)

\(=\frac{10}{24}-\frac{11}{24}\)

\(=-\frac{1}{24}\)

Answer 5

Bài làm 

\(\frac{5}{12}\)- \(\frac{7}{12}\): \(\frac{14}{11}\)

= \(\frac{5}{12}\) - \(\frac{11}{24}\)

= \(\frac{10}{24}\) - \(\frac{11}{24}\)

= \(\frac{-1}{24}\)

Answer 8

\(\frac{5}{12}-\frac{7}{12}:\frac{14}{11}\)

\(=\frac{5}{12}-\frac{7}{12}\times\frac{11}{14}\)

\(=\frac{5}{12}-\frac{7\times11}{12\times7\times2}\)

\(=\frac{5}{12}-\frac{11}{24}\)

\(=\frac{10}{24}-\frac{11}{24}=\frac{-1}{24}\)
