To determine which of the two options is a proportion, we need to check if the cross products are equal for each option.
A proportion states that two ratios are equal, meaning that if we have the ratio \( \frac{a}{b} = \frac{c}{d} \), then the cross products \( a \cdot d \) should equal \( b \cdot c \).
Let's evaluate both options:
Option 1: \( \frac{7}{8} = \frac{20}{22} \)
Cross products:
- \( 7 \times 22 = 154 \)
- \( 8 \times 20 = 160 \)
Since \( 154 \neq 160 \), Option 1 is not a proportion.
Option 2: \( \frac{7}{8} = \frac{21}{24} \)
Cross products:
- \( 7 \times 24 = 168 \)
- \( 8 \times 21 = 168 \)
Since \( 168 = 168 \), Option 2 is a proportion.
So, the answer is: Option 2 is a proportion.
