A. Show that the given ratios are equivalent by identifying their lowest terms. Write NE if the given ratios are not equivalent.
1. \( \frac{3}{6}, \frac{27}{54} \)
3. \( \frac{17}{34}, \frac{1}{2} \)
5. \( \frac{4}{12}, \frac{5}{15}, \frac{9}{27} \)
2. \( \frac{4}{6}, \frac{18}{27} \)
4. \( \frac{15}{45}, \frac{25}{95}, \frac{5}{25} \)
