Unlocking the Mystery: 4 is 12.5% of What Number?

Ever encountered a question like "4 is 12.5% of what number?" and felt a bit lost? You're not alone! This type of problem, commonly found in math and everyday situations, can be tackled with a simple formula and a bit of understanding.

Let's break down the process and see how we can solve this puzzle.

Understanding the Relationship

The core of this problem lies in the relationship between percentages, fractions, and whole numbers. When we say "12.5%," we're essentially representing a portion of a larger whole. In this case, we know the portion (4) and the percentage (12.5%), and we need to find the whole.

The Formula: A Powerful Tool

To find the whole number, we can use a simple formula:

Whole Number = (Portion / Percentage) * 100

Applying the Formula

1. Convert the percentage to a decimal: Divide 12.5 by 100, giving us 0.125.

2. Substitute the values:

   • Whole Number = (4 / 0.125) * 100

3. Calculate the result:

   • Whole Number = 32 * 100
   • Whole Number = 3200

The Answer

Therefore, 4 is 12.5% of 3200.

Practical Applications

This type of calculation comes in handy in various scenarios:

• Calculating Sales Tax: If you know the amount of sales tax you paid (the portion) and the sales tax rate (the percentage), you can find the original price of the item (the whole).

• Determining Discounts: If you know the discount amount (the portion) and the discount percentage (the percentage), you can determine the original price (the whole).

• Analyzing Data: In business and finance, understanding percentages helps analyze data and make informed decisions.

Beyond the Basics

While the formula is straightforward, understanding the concept of percentages is crucial. Remember that a percentage is just a fraction out of 100. So, 12.5% is equivalent to 12.5/100, which further simplifies to 0.125.
