About Mixed Numbers and Improper Fractions
A mixed number combines a whole number with a proper fraction (e.g., 2 1/3, 3 3/4). It represents quantities greater than one in an easy-to-understand format.
An improper fraction is a fraction where the numerator is greater than or equal to the denominator (e.g., 7/3, 15/4).
Converting mixed numbers to improper fractions is essential for performing mathematical operations like multiplication and division with fractions.
Key Definitions
• Mixed Number: Whole number + Proper fraction
• Improper Fraction: Numerator ≥ Denominator
• Proper Fraction: Numerator < Denominator
• Whole Number: The integer part of a mixed number
• Simplification: Reducing to lowest terms using GCD
How to Convert Mixed Numbers to Improper Fractions
Conversion Steps
- Multiply the whole number by the denominator - This gives you the base numerator value
- Add the numerator to the result - This creates your new numerator
- Keep the same denominator - The denominator stays unchanged
- Simplify if needed - Reduce the fraction to lowest terms using GCD
Example 1: Convert 2 1/3
Step 1: 2 × 3 = 6
Step 2: 6 + 1 = 7
Step 3: Denominator = 3
Result: 7/3
Example 2: Convert 3 3/4
Step 1: 3 × 4 = 12
Step 2: 12 + 3 = 15
Step 3: Denominator = 4
Result: 15/4
