Solve the Ratio Problem: Converting 20:1 to Standard Form

The problem asks us to divide 20 by 1. Let's solve this step-by-step:

• Step 1: Identify the operation required, which is division.
• Step 2: Recall the property of division by 1: dividing any number by 1 results in the number itself.
• Step 3: Apply this property to our problem: $\frac{20}{1}$.

Using the property of division, we have:

$\frac{20}{1} = 20$.

Therefore, the solution to the problem is 20.

The correct answer to the given multiple-choice question is choice 2: 20.
