Adding Fractions
a/b + c/d = (ad + bc) / bdTo add fractions, find a common denominator, then add the numerators. Simplify if possible.
Subtracting Fractions
a/b - c/d = (ad - bc) / bdTo subtract fractions, find a common denominator, then subtract the numerators.
Multiplying Fractions
a/b × c/d = (a × c) / (b × d)To multiply fractions, multiply the numerators together and multiply the denominators together.
Dividing Fractions
a/b ÷ c/d = a/b × d/c = (a × d) / (b × c)To divide fractions, multiply by the reciprocal (flip the second fraction and multiply).
Examples
Example 1: Add 1/4 + 2/3
(1×3 + 2×4) / (4×3) = (3 + 8) / 12 = 11/12 = 11/12
Example 2: Subtract 3/4 - 1/2
(3×2 - 1×4) / (4×2) = (6 - 4) / 8 = 2/8 = 1/4 = 1/4
Example 3: Multiply 2/3 × 3/4
(2 × 3) / (3 × 4) = 6/12 = 1/2 = 1/2
Example 4: Divide 1/2 ÷ 1/4
1/2 × 4/1 = 4/2 = 2 = 2
Frequently Asked Questions
Is this fraction calculator really free?
Yes! Our fraction calculator is 100% free with no hidden costs, no signup required, and no annoying popup ads. We believe math tools should be accessible to everyone.
How do I add fractions with different denominators?
Find the Least Common Denominator (LCD) of both fractions. Convert each fraction to have the LCD as the denominator, then add the numerators. Keep the common denominator and simplify if needed.
What is a proper vs improper fraction?
A proper fraction has a numerator smaller than the denominator (like 3/4). An improper fraction has a numerator equal to or larger than the denominator (like 5/4). Improper fractions can be converted to mixed numbers.
How do I simplify a fraction?
Find the Greatest Common Divisor (GCD) of the numerator and denominator, then divide both by the GCD. For example, to simplify 8/12: GCD is 4, so 8÷4 / 12÷4 = 2/3.
