What Does "Percent" Really Mean?

The word "percent" comes from the Latin "per centum," meaning "per hundred." Therefore, a percentage is simply a way of expressing a number as a fraction of 100. For example, 50% means 50 out of 100, or 50/100. This concept extends to whole numbers as well. In essence, converting a whole number to a percentage answers the question: "How many 'hundreds' are in this number?"

The Simple Method: Multiplying by 100

The easiest way to convert a whole number to a percentage is to multiply it by 100 and add the percent sign (%). This works because you are essentially expressing the whole number as a certain number of 'hundreds'.

Examples:

  • Convert 1 to a percentage: 1 * 100 = 100%. So, 1 is equal to 100%.
  • Convert 5 to a percentage: 5 * 100 = 500%. This means 5 is equal to five 'hundreds'.
  • Convert 25 to a percentage: 25 * 100 = 2500%.

Why Would You Convert a Whole Number to a Percentage?

While it might seem abstract, converting whole numbers to percentages has practical applications. Here are a few scenarios:

  • Expressing Growth: If your company's revenue doubled, you could say it increased by 100%. If it tripled, that's a 200% increase.
  • Comparing Values: Imagine you have 3 times more customers this year than last year. You can express that as a 300% of last year's customer base.
