To compare the ratios \( \frac{5}{9} \) and \( \frac{3}{6} \), we can first simplify \( \frac{3}{6} \):

\[ \frac{3}{6} = \frac{1}{2} \]

Next, we can check the ratio \( \frac{5}{9} \) in decimal form:

\[ \frac{5}{9} \approx 0.555... \]

Now we compare \( 0.555... \) to \( 0.5 \) (which is the decimal representation of \( \frac{1}{2} \)).

Now, let's analyze the provided tables to confirm the ratios:

For \( 5:9 \):

  • When \( 5 \) is compared to \( 9 \), it's a ratio of \( \frac{5}{9} \).
  • If we multiply \( 5 \) and \( 9 \) by the same number, their ratios remain equivalent:
    • \( 10:18 = \frac{10}{18} = \frac{5}{9} \)
    • \( 15:27 = \frac{15}{27} = \frac{5}{9} \)
    • \( 20:36 = \frac{20}{36} = \frac{5}{9} \)
    • \( 25:45 = \frac{25}{45} = \frac{5}{9} \)

For \( 3:6 \):

  • When \( 3 \) is compared to \( 6 \), it simplifies to \( \frac{1}{2} \).
  • Similarly, the other ratios will yield the same result:
    • \( 6:12 = \frac{6}{12} = \frac{1}{2} \)
    • \( 9:18 = \frac{9}{18} = \frac{1}{2} \)
    • \( 12:24 = \frac{12}{24} = \frac{1}{2} \)
    • \( 15:30 = \frac{15}{30} = \frac{1}{2} \)

Given that \( \frac{5}{9} \approx 0.555... \) is greater than \( \frac{1}{2} \), we can conclude:

\[ \frac{5}{9} > \frac{3}{6} \]

Thus, the ratio \( 5:9 \) is greater than \( 3:6 \).
