The decimal 0.5 is also equivalent to 50%. Therefore, the problem can be rephrased as:

50% of 490 = ?

To solve percentage problems, we can use the formula:

(Percentage/100) x Total Value = Result

Substituting the values from our problem:

(50/100) x 490 = 0.5 x 490 = 245

This method showcases the close relationship between decimals, fractions, and percentages, all representing different ways to express the same proportional relationship.

Practical Applications: Real-World Scenarios

Understanding the calculation of "0.5 of 490" extends far beyond simple arithmetic exercises. It finds application in a vast range of practical situations:

• Sales and Discounts: Imagine a store offering a 50% discount on an item priced at $490. The calculation of 0.5 x 490 = $245 directly determines the discount amount. The final price would be $490 - $245 = $245.

• Financial Calculations: Consider splitting a $490 bill equally between two people. Each person would pay 0.5 (or 1/2) of the total, which is $245.

• Measurement and Proportion: If a recipe calls for 490 grams of flour and you only want to make half the recipe, you would use 0.5 x 490 = 245 grams of flour.

• Data Analysis: In statistical analysis, calculating 50% of a data set is a common operation used to find the median or midpoint.

• Scientific Applications: Many scientific formulas involve calculating fractions or percentages of quantities. This fundamental skill is essential in fields ranging from chemistry and physics to biology and engineering.

Expanding the Concept: Beyond 0.5

While this article focuses on 0.5, the principles discussed extend to any fraction or decimal. Let's consider some variations:

• 0.25 of 490: This represents 25% or 1/4 of 490. The calculation would be 0.25 x 490 = 122.5

• 0.75 of 490: This represents 75% or 3/4 of 490. The calculation would be 0.75 x 490 = 367.5

• 0.1 of 490: This represents 10% of 490. The calculation would be 0.1 x 490 = 49

By understanding the core principles illustrated with 0.5, we can readily adapt these methods to solve any problem involving a fraction or percentage of a given number.
