Timeline: The Conversion Process

Let’s break down the steps to convert 4.5 into a fraction:

  1. Identify the Decimal: The given decimal is 4.5.
  2. Separate the Whole Number and the Decimal Part: Here, 4 is the whole number, and 0.5 is the decimal part.
  3. Convert the Decimal Part to a Fraction: 0.5 can be written as 5/10, which simplifies to 1/2.
  4. Combine the Whole Number and the Fraction: The whole number 4 can be written as 4/1. Adding this to 1/2, we get 4 + 1/2 = 8/2 + 1/2 = 9/2.

Thus, 4.5 as a fraction is 9/2.
