Understanding Mixed Numbers

A mixed number consists of a whole number part and a proper fraction part. For example, 3 1/2 means "three and a half" or 3 + 1/2.

Conversion between Mixed Numbers and Improper Fractions
  • Mixed to Improper: Multiply the whole number by the denominator, add the numerator, and keep the same denominator.
    Example: 2 3/4 = ((2 × 4) + 3)/4 = 11/4
  • Improper to Mixed: Divide the numerator by the denominator. The quotient is the whole number, and the remainder is the new numerator.
    Example: 11/4 = 2 3/4
Arithmetic Operations with Mixed Numbers
  • Addition/Subtraction: Convert to fractions with a common denominator, add/subtract the numerators, then convert back to a mixed number.
  • Multiplication: Convert mixed numbers to improper fractions, multiply the numerators and denominators, then simplify.
  • Division: Convert mixed numbers to improper fractions, multiply by the reciprocal of the divisor, then simplify.
Simplifying Fractions

To simplify a fraction, divide both the numerator and denominator by their greatest common divisor (GCD).

Example: 8/12 simplifies to 2/3 (both 8 and 12 can be divided by 4)

Note: This calculator follows standard mathematical conventions for mixed number arithmetic. Results are always presented in simplified form.

Mixed to Improper Fraction:
\( \text{Improper Fraction} = \frac{(\text{Whole Number} \times \text{Denominator}) + \text{Numerator}}{\text{Denominator}} \)

Improper to Mixed Number:
\( \text{Mixed Number} = \text{Whole Number} + \frac{\text{Remainder}}{\text{Denominator}} \)

Adding/Subtracting Fractions:
\( \frac{a}{b} \pm \frac{c}{d} = \frac{ad \pm bc}{bd} \)

Multiplying Fractions:
\( \frac{a}{b} \times \frac{c}{d} = \frac{ac}{bd} \)

Dividing Fractions:
\( \frac{a}{b} \div \frac{c}{d} = \frac{a \times d}{b \times c} \)
