Answer 3

\(\frac{5}{4}-\frac{4}{5}\times\frac{4}{3}\)

\(=\frac{5}{4}-\frac{16}{15}\)

\(=\frac{11}{60}\)

\(\frac{3}{7}:\frac{1}{2}\times\frac{14}{15}\)

\(=\frac{3}{7}\times\frac{2}{1}\times\frac{14}{15}\)

\(=\frac{4}{5}\)

\(\frac{2}{5}+x=\frac{6}{7}\)

           \(x=\frac{6}{7}-\frac{2}{5}\)

           \(x=\frac{16}{35}\)

\(\frac{1}{3}:x=\frac{8}{9}\)

       \(x=\frac{1}{3}:\frac{8}{9}\)

       \(x=\frac{3}{8}\)
