How to Calculate Fractions
Adding Fractions
To add fractions, you must find a common denominator.
Formula: (a/b) + (c/d) = (ad + bc) / bd
Subtracting Fractions
Similar to addition, requires a common denominator.
Formula: (a/b) - (c/d) = (ad - bc) / bd
Multiplying Fractions
Multiply the numerators together and the denominators together.
Formula: (a/b) × (c/d) = (ac) / (bd)
Dividing Fractions
Multiply the first fraction by the reciprocal (flip) of the second.
Formula: (a/b) ÷ (c/d) = (a/b) × (d/c) = (ad) / (bc)
? Frequently Asked Questions
A mixed number combines a whole number and a fraction, like 1 1/2. It represents the same value as an improper fraction (where the top is bigger than the bottom), like 3/2.
Divide both the numerator (top) and denominator (bottom) by their Greatest Common Divisor (GCD). For example, 4/8 simplifies to 1/2 because both can be divided by 4.
No. Division by zero is undefined in mathematics. A fraction represents parts of a whole, and you cannot split a whole into zero parts.
