Answer 2

\(\frac{4}{16}+\frac{6}{15}+\frac{8}{14}+\frac{3}{7}+\frac{3}{5}+\frac{3}{4}\)

\(=\frac{1}{4}+\frac{2}{5}+\frac{4}{7}+\frac{3}{7}+\frac{3}{5}+\frac{3}{4}\)

\(=\left(\frac{1}{4}+\frac{3}{4}\right)+\left(\frac{2}{5}+\frac{3}{5}\right)+\left(\frac{4}{7}+\frac{3}{7}\right)\)

\(=\frac{4}{4}+\frac{5}{5}+\frac{7}{7}\)

\(=1+1+1\)

\(=3\)
