Practical Examples
Let’s look at a few practical examples to illustrate the conversion of 7⁄2 to a decimal and its applications:
Example 1: Calculating a Discount
Suppose you are shopping and find an item priced at 14. The store offers a discount of 7/2 percent on the item. To calculate the discount amount:</p> <ol> <li>Convert the fraction 7/2 to a decimal: 3.5%</li> <li>Calculate 3.5% of 14: (3.5⁄100) * 14 = 0.49
Example 2: Measuring Ingredients
In a recipe, you need to measure 7⁄2 cups of flour. To convert this to a decimal:
- Convert the fraction 7⁄2 to a decimal: 3.5 cups
- Measure 3.5 cups of flour using a measuring cup.
Example 3: Calculating BMI
To calculate your Body Mass Index (BMI), you need to divide your weight in kilograms by the square of your height in meters. Suppose your weight is 70 kg and your height is 1.75 meters. To find your BMI:
- Calculate the square of your height: 1.75 * 1.75 = 3.0625
- Divide your weight by the square of your height: 70 / 3.0625 ≈ 22.86
- Your BMI is approximately 22.86.
Conclusion
