A proportion is an equation that states that two ratios are equal.

To determine whether either of the options is a proportion, we can simplify each fraction and compare them to the whole number.

  1. Option 1: \( 56 = \frac{15}{18} \)
    Simplifying \( \frac{15}{18} \):
    \( \frac{15 \div 3}{18 \div 3} = \frac{5}{6} \)
    So, we have:
    \( 56 \neq \frac{5}{6} \)

  2. Option 2: \( 56 = \frac{20}{18} \)
    Simplifying \( \frac{20}{18} \):
    \( \frac{20 \div 2}{18 \div 2} = \frac{10}{9} \)
    So, we have:
    \( 56 \neq \frac{10}{9} \)

Since neither left side equals the simplified fraction on the right side, neither option represents a true proportion.

Therefore, neither Option 1 nor Option 2 is a proportion.

If you meant that one of these is "implying a proportional relationship" by matching with a ratio, consider the ratio of the numbers instead of the equality. But strictly speaking, as written, neither qualifies as a proportion.

Please clarify if you need something else!
