Convert 40/100 to Percentage: Step-by-Step Calculation

Question

Calculate 40 over 100 as a percentage:

In order to determine what percentage 40 is out of 100, we use the following formula:

$\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100$

We begin by substituting in the known values:

$\text{Percentage} = \left( \frac{40}{100} \right) \times 100$

We then proceed to solve the expression:

$\text{Percentage} = 0.4 \times 100$

$\text{Percentage} = 40$

Thus, 40 out of 100 is 40%.
