So, how exactly do you convert a fraction into a percent? Let's break it down.

Understanding Fractions and Percents

Before diving into the conversion process, it's crucial to understand what fractions and percents represent.

  • Fraction: A fraction represents a part of a whole, expressed as a ratio between two numbers – the numerator (top number) and the denominator (bottom number). For example, in the fraction 3⁄4, 3 is the numerator, and 4 is the denominator.
  • Percent: Percent means "per hundred" or "out of one hundred." It's a way of expressing a number as a fraction of 100. The symbol "%" represents percent.

Methods for Turning a Fraction Into a Percent

There are primarily two methods for converting fractions to percents:

Method 1: Creating an Equivalent Fraction with a Denominator of 100

This method is most suitable when the denominator of the fraction is a factor or multiple of 100. The goal is to create an equivalent fraction where the denominator is 100.

  1. Find the Multiplier: Determine what number you need to multiply the original denominator by to get 100.
  2. Multiply Numerator and Denominator: Multiply both the numerator and the denominator of the fraction by this multiplier.
  3. Express as a Percent: The new numerator represents the percentage.

Example: Convert 13⁄20 to a percentage.

  • Multiplier: 20 * 5 = 100
  • Multiply: (13 * 5) / (20 * 5) = 65⁄100
  • Percent: 65%

Method 2: Dividing and Multiplying by 100

This method works for any fraction, regardless of its denominator.

  1. Divide: Divide the numerator of the fraction by its denominator to obtain a decimal.
  2. Multiply by 100: Multiply the decimal by 100.
  3. Add the Percent Symbol: Affix the "%" symbol to the result.

Example: Convert 2⁄5 to a percentage.

  • Divide: 2 ÷ 5 = 0.4
  • Multiply: 0.4 * 100 = 40
  • Percent: 40%

Real-World Applications

Converting fractions to percentages has numerous applications. Consider these scenarios:

  • Test Scores: A student scores 43 out of 50 on a test. Converting 43⁄50 to a percentage (86%) provides a clear understanding of their performance.
  • Discounts: A store offers a discount of 1⁄4 off the original price. Knowing this is 25% helps customers quickly assess the savings.
  • Resource Allocation: An IT department reports that 7⁄8 of the network bandwidth is being utilized. This translates to 87.5%, indicating a high level of usage.
