Mathematical Formulas & Calculation Methods

Fraction Addition & Subtraction (LCD Formula)

Uses common denominator LCD to combine numerators.

(a/b) ± (c/d) = (ad ± bc) / bd

Worked Step-by-Step Examples

Example 1: Adding 3/4 + 2/5

"Calculate simplified sum and decimal equivalent."

Steps:

LCD Denominator = 4 × 5 = 20.
Numerator = (3 × 5) + (2 × 4) = 15 + 8 = 23.
Unsimplified Fraction = 23/20.
Mixed Number = 1 3/20 | Decimal = 1.15.

Result: 23/20 or 1 3/20 (Decimal: 1.15)
