What is a Mixed Number?

Before we begin, let's clarify what a mixed number is. A mixed number combines a whole number and a fraction. In our case, 1 and 1/2 means one whole unit plus one-half of another unit.

Converting 1 and 1/2 to a Decimal: Step-by-Step

Here's how to easily convert 1 and 1/2 to a decimal:

Step 1: Understand the Parts

The mixed number 1 and 1/2 consists of two parts: the whole number (1) and the fraction (1/2).

Step 2: Convert the Fraction

The fraction 1/2 represents one part out of two equal parts. To convert it to a decimal, divide the numerator (1) by the denominator (2):

1 ÷ 2 = 0.5

Step 3: Combine the Whole Number and Decimal

Now, combine the whole number from Step 1 with the decimal from Step 2:

1 + 0.5 = 1.5

Therefore, 1 and 1/2 as a decimal is 1.5.

Why is this Conversion Important?

Understanding this conversion is crucial for various reasons:

Everyday Calculations: Many everyday calculations, such as those involving money or measurements, require working with decimals. Converting fractions to decimals simplifies these calculations. For example, if an item costs 1 and 1/2 dollars, it's easier to work with $1.50.
