Very large integers ke liye BigInt operations use kiye gaye hain.
Addition/Subtraction: Find common denominator using LCM, convert fractions, add/subtract numerators, simplify.
Example: 3/4 + 1/6 = (3×6)/(4×6) + (1×4)/(6×4) = 22/24 = 11/12
Multiplication: Multiply numerators and denominators, then simplify.
Example: 3/4 × 1/6 = (3×1)/(4×6) = 3/24 = 1/8
Division: Multiply by the reciprocal of the second fraction.
Example: 3/4 ÷ 1/6 = 3/4 × 6/1 = 18/4 = 9/2
Simplification: Divide numerator and denominator by their GCD.
Example: 220/440 → GCD=220 → 220÷220/440÷220 = 1/2
Decimal Conversion: For fraction to decimal, divide numerator by denominator. For decimal to fraction, use continued fractions or direct method for terminating decimals.
Example: 0.1234 = 1234/10000 = 617/5000
This Fraction Calculator helps you solve fraction problems instantly with step-by-step working. You can calculate common operations like addition, subtraction, multiplication, and division, and also convert between fractions and decimals, simplify results, and work with mixed numbers.
Whether you’re solving homework, checking exam answers, or doing quick real-life math (recipes, measurements, discounts), this tool shows a clean result in simplified fraction form plus the decimal value.
To add or subtract fractions, you need a common denominator (often found using LCM). Convert both fractions, then add/subtract the numerators.
Formula: a/b ± c/d = (ad ± bc) / bd
Multiply numerators together and denominators together, then simplify.
Formula: (a/b) × (c/d) = (ac)/(bd)
Divide by multiplying the first fraction by the reciprocal of the second fraction.
Formula: (a/b) ÷ (c/d) = (a/b) × (d/c)
A fraction is simplified when the numerator and denominator share no common factor other than 1. Divide both by their GCD (greatest common divisor).
To simplify a fraction, find the GCD of numerator and denominator, then divide both by that GCD. This gives the simplest form.
This page also shows the mixed-number form when applicable (like 9/2 = 4 1/2).
Mixed numbers look like 2 3/4. This tool converts mixed numbers into improper fractions, performs the operation, simplifies the result, and converts back to mixed form.
Convert decimals like 1.375 into an exact fraction. For terminating decimals, the method is simple: write it over 10, 100, 1000… then simplify. For long decimals, the calculator approximates using efficient methods.
To convert a fraction into decimal, divide numerator by denominator. This page shows a rounded decimal output (useful for quick checking).
3/4 + 1/6 = (3×6 + 1×4) / 24 = 22/24 = 11/12
3/4 × 1/6 = 3/24 = 1/8
3/4 ÷ 1/6 = 3/4 × 6/1 = 18/4 = 9/2 (4 1/2)
220/440 → divide numerator & denominator by 220 → 1/2
Because fractions represent parts of a whole. To add/subtract them correctly, both fractions must be expressed in the same “type of parts” (same denominator). LCM helps find the smallest common denominator.
Multiply the first fraction by the reciprocal of the second fraction. Example: (2/3) ÷ (5/7) = (2/3) × (7/5).
A fraction is in simplest form when numerator and denominator have no common factor other than 1.
Decimal form is useful for comparisons and quick estimates. The fraction form is best for exact answers.
Division by zero is undefined, so the calculator will show an error/invalid result.
This fraction calculator is for educational and informational purposes only. Results may vary slightly due to rounding (especially for long repeating decimals). Always verify answers if you’re using them for exams or official work.
