Solve for Original Value: Finding Whole Number When 40% Equals 2

To solve this problem, we'll follow these steps:

• Step 1: Convert the given percentage to a decimal by dividing by 100.

• Step 2: Use the formula to find the whole number based on the part and the percentage in decimal form.

• Step 3: Verify that the calculated whole corresponds to the multiple choice answers provided.

Now, let's work through each step:
Step 1: Convert 40% to decimal form. This gives us $0.40$.
Step 2: Use the formula for the whole:
$\text{Whole} = \frac{\text{Part}}{\text{Percentage in decimal}} = \frac{2}{0.40}$ Calculate this division: $\frac{2}{0.40} = 5$
Step 3: Verify: The whole number calculated is 5, a valid option in the multiple-choice answers.
Therefore, the solution to the problem is $5$.
