Understanding the Percentage Formula

The core of any percentage calculation lies in this simple formula:

(Part / Whole) x 100% = Percentage

In our case:

• Part: 3
• Whole: 13

Step-by-Step Calculation: What Percentage is 3 of 13?

1. Divide the Part by the Whole: We begin by dividing the part (3) by the whole (13):

   3 / 13 ≈ 0.2308

2. Multiply by 100: To convert the decimal to a percentage, we multiply the result by 100:

   0.2308 x 100% = 23.08%

3. Round (Optional): Depending on the level of precision needed, you might round the percentage. Rounding to one decimal place, we get 23.1%. Rounding to the nearest whole number gives us 23%.

Therefore, 3 is approximately 23.1% of 13.
