Answer 1

$$\begin{gathered} \frac{3}{5}+\frac{3}{8}÷\frac{6}{4} \\ =\frac{3}{5}+\frac{3}{8}\times \frac{4}{6} \\ =\frac{3}{5}+\frac{1}{4} \\ =\frac{4\times 3+5\times 1}{20}\left(\mathrm{Since},\mathrm{LCM}\mathrm{of}5\mathrm{and}4\mathrm{is}20\right) \\ =\frac{12+5}{20} \\ =\frac{17}{20} \end{gathered}$$
