Question
Which of the following, Option 1 or Option 2, is a proportion?

Option 1: 56=1518


Option 2: 56=2018


(1 point)
Option
is a proportion.

Answer 1

To determine which option is a proportion, we need to check if the two ratios in each option are equivalent.

**Option 1: \( \frac{56}{15} = \frac{18}{1} \)**

Cross-multiplying gives:
\( 56 \times 1 = 18 \times 15 \)

Calculating both sides:
- Left side: \( 56 = 56 \)
- Right side: \( 18 \times 15 = 270 \)

Since \( 56 \neq 270 \), Option 1 is **not** a proportion.

---

**Option 2: \( \frac{56}{20} = \frac{18}{1} \)**

Cross-multiplying gives:
\( 56 \times 1 = 18 \times 20 \)

Calculating both sides:
- Left side: \( 56 = 56 \)
- Right side: \( 18 \times 20 = 360 \)

Since \( 56 \neq 360 \), Option 2 is also **not** a proportion.

---

Thus, neither option is a proportion, but if you need to select one based on the definitions and values provided:

You could state **both options are not proportions**. However, if the assignment provides a direct choice without needing to state that neither is correct, please clarify further or check if other defining characteristics were provided in your materials.
