Fractions and decimals are two ways to represent the same value. Knowing how to convert between them is a useful skill in math and everyday life. This guide will show you exactly how to convert the mixed number 1 1/2 into a decimal.

Understanding Mixed Numbers and Decimals

Before we begin, let's quickly review what mixed numbers and decimals are:

Mixed Number: A mixed number combines a whole number and a fraction (e.g., 1 1/2, 3 2/5).
Decimal: A decimal is a number expressed using a decimal point, separating the whole number part from the fractional part (e.g., 1.5, 3.4).

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

Converting 1 1/2 to a decimal involves two simple steps:

Step 1: Convert the Fraction to a Decimal

The first step is to convert the fractional part of the mixed number (1/2) into a decimal. To do this, you divide the numerator (the top number) by the denominator (the bottom number):

1 ÷ 2 = 0.5

Step 2: Add the Whole Number

Now that you have the decimal equivalent of the fraction (0.5), add it to the whole number part of the mixed number (1):

1 + 0.5 = 1.5

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

Other Methods for Converting Fractions to Decimals

While the above method is straightforward for simple fractions like 1/2, other methods exist for more complex fractions:

Using Equivalent Fractions: Some fractions can be easily converted to decimals by finding an equivalent fraction with a denominator that is a power of 10 (10, 100, 1000, etc.). For example, 1/4 can be converted to 25/100, which is 0.25.
Long Division: For more complex fractions, long division provides a reliable method for finding the decimal equivalent. This involves dividing the numerator by the denominator.

Practical Applications of Decimal Conversions

Converting fractions to decimals is useful in many real-world situations:

Calculating Prices: Discounts, sales tax, and unit pricing often involve decimals.
Measuring: Many measuring tools utilize decimal systems.
Financial Calculations: Interest rates, investments, and budgets frequently use decimal values.
Scientific Calculations: Decimals are fundamental to various scientific computations.

Conclusion

Converting 1 1/2 to a decimal is a simple process. By following the steps outlined above, you can easily convert this and other mixed numbers into their decimal equivalents. Understanding these conversions enhances your mathematical skills and allows you to navigate various numerical applications with ease. Remember that 1 1/2 is equal to 1.5 in decimal form.
