Understanding how to convert fractions to decimals is a fundamental skill in math. This article will show you exactly how to convert the mixed number 1 and 1/2 into its decimal equivalent. We'll break down the process step-by-step, making it easy to understand, regardless of your math background.

Understanding Mixed Numbers and Decimals

Before we dive into the conversion, let's quickly review what mixed numbers and decimals represent.

Mixed Numbers: A mixed number combines a whole number and a fraction (e.g., 1 and 1/2, 2 and 3/4). It represents a value greater than one.
Decimals: Decimals use a base-ten system to represent numbers less than one. The decimal point separates the whole number from the fractional part (e.g., 0.5, 1.75).

Converting 1 and 1/2 to a Decimal

There are two main ways to convert 1 and 1/2 to a decimal:

Method 1: Converting the Fraction First

Convert the fraction to a decimal: The fraction 1/2 represents one part out of two equal parts. Dividing 1 by 2 gives you 0.5.
Add the whole number: Now, add the whole number (1) to the decimal value of the fraction (0.5). This gives you 1 + 0.5 = 1.5.

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

Method 2: Converting to an Improper Fraction First

Convert to an improper fraction: To do this, multiply the whole number (1) by the denominator (2), then add the numerator (1). This gives you (1 x 2) + 1 = 3. Keep the same denominator (2). So, 1 and 1/2 becomes 3/2.
Divide the numerator by the denominator: Divide 3 by 2. This gives you 1.5.

Again, we arrive at the answer: 1 and 1/2 as a decimal is 1.5.

Why is this Conversion Important?

Understanding how to convert fractions to decimals is crucial for various applications:

Everyday Calculations: Many everyday tasks, such as calculating tips, measuring ingredients, or working with money, involve decimals.
Advanced Math: Decimals are fundamental to more advanced math concepts like algebra and calculus.
Data Analysis: In data science and statistics, data is often represented using decimals.

Practice Makes Perfect

Try converting other mixed numbers to decimals using these methods. The more you practice, the easier it will become! For example, try converting 2 and 3/4 or 3 and 1/5 to decimals. Remember to break down the process step-by-step, and you'll master this skill in no time.

Conclusion

Converting 1 and 1/2 to a decimal is a straightforward process. By following the simple steps outlined above, you can confidently convert this and other mixed numbers to their decimal equivalents. This fundamental skill is invaluable in various mathematical applications and everyday life. Remember, 1 and 1/2 is equal to 1.5 in decimal form.
