Answer 3

\(\frac{14}{27}:\frac{7}{18}x\frac{6}{5}+\frac{3}{10}=\frac{4}{3}x\frac{6}{5}+\frac{3}{10}=\frac{8}{5}+\frac{3}{10}=\frac{19}{10}\)

Answer 4

\(\frac{14}{27}:\frac{7}{18}.\frac{6}{5}+\frac{3}{10}=\frac{14}{27}.\frac{18}{7}.\frac{6}{5}+\frac{3}{10}\)

                                       \(=\frac{4}{3}.\frac{6}{5}+\frac{3}{10}=\frac{4.6}{3.5}+\frac{3}{10}\)

                                            \(=\frac{24}{15}+\frac{3}{10}=\frac{8}{5}+\frac{3}{10}=\frac{16}{10}+\frac{3}{10}\)

\(=\frac{16+3}{10}=\frac{19}{10}\)
