3. Final Result: 1 + 0.375 = 1.375

Therefore, 1 and 3/8 as a decimal is 1.375.

Understanding Fractions and Decimals:

Fractions and decimals are simply different ways of representing the same value. A fraction expresses a part of a whole, while a decimal uses a base-ten system to represent the same part. Understanding the relationship between them is crucial for mathematical proficiency. Other examples of common fraction to decimal conversions include:

• 1/2 = 0.5
• 1/4 = 0.25
• 3/4 = 0.75
• 1/10 = 0.1

Practical Applications:

Converting fractions to decimals is essential in various real-world applications, including:

• Measurement: Converting measurements from fractions of inches or centimeters to decimal values.
• Finance: Calculating percentages, interest rates, and other financial figures.
• Engineering: Precision calculations in design and manufacturing processes often require decimal representation.
• Data Analysis: Working with datasets that contain both fractional and decimal values.

Mastering fraction to decimal conversions will enhance your problem-solving skills and improve your overall mathematical abilities. This simple yet vital skill is widely applicable and contributes to a stronger foundational understanding of numbers. Remember the basic process: divide the numerator by the denominator and add the whole number for mixed numbers. Practice this conversion with different fractions to build confidence and fluency.
