What is x percent of y?

Answer: To find what ( x )% of ( y ) is, you can use the following formula:

\text{Percentage Value} = \frac{x}{100} \times y

Here, ( x ) is the percentage you want to find, and ( y ) is the total amount from which you’re taking the percentage.

Example Calculation:

Let’s go through an example to make it clear:

Example: What is 20% of 50?

  1. Identify the values: ( x = 20 ) and ( y = 50 ).

  2. Use the formula:

\text{Percentage Value} = \frac{20}{100} \times 50
  1. Perform the calculation:
\text{Percentage Value} = 0.2 \times 50 = 10

So, 20% of 50 is 10.

Understanding the Concept:

Taking a percentage of a number essentially means you’re finding a portion of that number proportional to 100. Here are some other quick examples:

  • What is 30% of 90?

    \text{Percentage Value} = \frac{30}{100} \times 90 = 0.3 \times 90 = 27

  • What is 75% of 200?

    \text{Percentage Value} = \frac{75}{100} \times 200 = 0.75 \times 200 = 150

Practical Applications:

Knowing how to calculate percentages is useful in many real-life situations, including:

  • Sales and Discounts: Calculating how much money you save during a sale.
  • Statistics: Understanding data and probabilities.
  • Finance: Calculating interest rates, loan payments, and investment returns.
  • Health and Fitness: Determining nutritional values or workout intensities.

Tips for Quick Calculations:

  • 10% of any number: Move the decimal point one place to the left.
    • Example: 10% of 50 is 5.
  • 5% of any number: First, find 10% and then divide by 2.
    • Example: 5% of 50 is 2.5.
  • 1% of any number: Move the decimal point two places to the left.
    • Example: 1% of 50 is 0.5.

By mastering these calculations, you’ll find it easier to handle many numeric problems in everyday life.
