Una sustancia radiactiva se descompone un 10% cada día. Si la masa inicial es de 500 gramos, ¿cuál será la masa después de 7 días?
La sustancia se descompone un 10% cada día, por lo que el factor de descomposición es \(1 - 0.10 = 0.90\).
Después de 1 día: \(500 \times 0.90 = 450\) gramos.

Why This Calculation Matters — Real-World Applications

1. Cooking and Recipe Scaling

If a recipe serves 10 people and calls for 2,500 grams of a key ingredient, knowing that 5% of that amount is 125 grams helps in scaling portions or adjusting servings precisely.

2. Nutrition and Dietary Planning

Understanding how percentages translate into grams helps monitor calorie or nutrient intake. For example, 5% of a food item’s weight might represent its protein, fat, or carbohydrate content.

3. Manufacturing and Material Costs

Engineers and material scientists use such calculations daily to determine exact quantities needed for production, reducing waste and optimizing resource use.

How to Do This Calculation Fast (Mental Math Trick)

You don’t always need a calculator. Recognizing that:

  • 0.05 × X = (5/100) × X = (X ÷ 20)
    So     0.05 × 2,500 = 2,500 ÷ 20 = 125.
    This mental shortcut speeds up everyday math.
