Put these fractions in order from least to greatest: \(\frac{7}{35}, \frac{40}{50}, \frac{8}{20}, \frac{3}{5} , \frac{25}{5}\)
 \(\frac{3}{5}, \frac{7}{35}, \frac{8}{20}, \frac{25}{5}, \frac{40}{50}\)
 \(\frac{3}{5}, \frac{25}{5}, \frac{8}{20}, \frac{7}{35}, \frac{40}{50}\)
 \(\frac{3}{5}, \frac{8}{20}, \frac{25}{5}, \frac{7}{35}, \frac{40}{50}\)
 \(\frac{25}{5}, \frac{40}{50}, \frac{3}{5}, \frac{8}{20}, \frac{7}{35}\)
 None of the above
