What is a Fraction?

Before we dive into converting 4.5 to a fraction, let's quickly review what a fraction is. A fraction is a way of expressing a part of a whole as a ratio of two numbers. It consists of a numerator (the top number) and a denominator (the bottom number). For example, 3/4 is a fraction where 3 is the numerator and 4 is the denominator.

Why Convert Decimals to Fractions?

Converting decimals to fractions is an essential skill in mathematics, as it allows us to perform various mathematical operations, such as addition, subtraction, multiplication, and division, with ease. Fractions are also used to express proportions, rates, and ratios, which are crucial in many real-world applications, such as science, engineering, and finance.

Converting 4.5 to a Fraction

Now, let's convert the decimal number 4.5 to a fraction in simplest form. To do this, we can use the following steps:

1. Identify the Whole Number Part: The whole number part of 4.5 is 4.
2. Find the Decimal Part: The decimal part of 4.5 is 0.5.
3. Determine the Denominator: Since the decimal part is 0.5, we can use 10 as the denominator (because 0.5 = 5/10).
4. Write the Fraction: Combine the whole number part (4) with the fraction part (5/10) to get 4 5/10.

Simplifying the Fraction

The fraction 4 5/10 can be simplified further. To do this, we can divide both the numerator (5) and the denominator (10) by 5, which gives us:

4 1/2

And that's it! The decimal number 4.5 can be expressed as a fraction in simplest form as 4 1/2.
