Answer 1

\(\frac{\frac{2}{7}+\frac{2}{17}+\frac{2}{37}}{\frac{5}{7}+\frac{5}{17}+\frac{5}{37}}\)

\(=\frac{2\left(\frac{1}{7}+\frac{1}{17}+\frac{1}{37}\right)}{5\left(\frac{1}{7}+\frac{1}{17}+\frac{1}{37}\right)}\)

\(=\frac{2}{5}\)

Answer 2

2/7+2/17+2/37/ 5/7+5/17+5/37

= 2(1/7+1/17+1/37)/ 5(1/7+1/17+1/37)

= 2/5
