Converting fractions to decimals is a fundamental skill in mathematics. This guide will walk you through converting the mixed number 1 1/2 into its decimal equivalent. We'll cover the process step-by-step, making it easy to understand, even for beginners.

Understanding Mixed Numbers and Decimals

Before we begin, let's quickly review what mixed numbers and decimals represent.

A mixed number combines a whole number and a fraction, like 1 1/2. This means one whole unit plus one-half of another unit.

A decimal is a number expressed using a base-ten system, where a decimal point separates the whole number part from the fractional part. For example, 2.5 is a decimal representing two and five-tenths.

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

Here's how to convert 1 1/2 to its decimal form:

Step 1: Convert the Fraction to a Decimal

The first step involves converting the fractional part (1/2) into a decimal. To do this, divide the numerator (the top number) by the denominator (the bottom number).

1 ÷ 2 = 0.5

Step 2: Add the Whole Number

Now, simply add the whole number part of the mixed number (1) to the decimal you just calculated (0.5).

1 + 0.5 = 1.5

Therefore, 1 1/2 as a decimal is 1.5

Why is this Conversion Important?

Understanding how to convert fractions to decimals is crucial for several reasons:

Everyday Calculations: Many everyday situations require decimal calculations, such as measuring ingredients in a recipe, calculating costs, or understanding percentages.
Mathematical Applications: Decimals are essential in various mathematical fields, including algebra, calculus, and statistics. Being able to seamlessly convert between fractions and decimals enhances your problem-solving abilities.
Data Interpretation: Many data sets and graphs use decimals. The ability to convert fractions simplifies understanding and interpreting such data.

Other Examples: Converting Mixed Numbers to Decimals

Let's look at a few more examples to solidify your understanding:

2 1/4: 1/4 = 0.25; 2 + 0.25 = 2.25
3 3/5: 3/5 = 0.6; 3 + 0.6 = 3.6
1 7/10: 7/10 = 0.7; 1 + 0.7 = 1.7

Tips for Converting Fractions to Decimals

Simplify the Fraction: If possible, simplify the fraction before performing the division. This makes the calculation easier.
Use a Calculator: For more complex fractions, a calculator can be a helpful tool.
Practice: The best way to master this skill is through regular practice.

Conclusion

Converting 1 1/2 to a decimal, resulting in 1.5, is a straightforward process. By understanding the steps involved and practicing with various examples, you'll quickly build confidence in handling fraction-to-decimal conversions. This skill is invaluable for both everyday calculations and more advanced mathematical applications. Remember that mastering this simple conversion forms a solid foundation for more complex mathematical concepts.
