How do you multiply fractions online?

Multiplying fractions is simple: multiply the numerators together and multiply the denominators together. Example: 2/3 × 3/4 = (2×3)/(3×4) = 6/12 = 1/2 (simplified). Use our free fraction multiplier above for instant results.

How do you divide fractions step by step?

To divide fractions, flip the second fraction (find its reciprocal) and then multiply. Example: 2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12 = 5/6. This is sometimes remembered as 'Keep, Change, Flip' (KCF).

How do you simplify a fraction to lowest terms?

To simplify a fraction, find the Greatest Common Divisor (GCD) of the numerator and denominator, then divide both by it. Example: 12/18 → GCD is 6 → 12÷6 / 18÷6 = 2/3. Our simplify fraction calculator does this instantly.

Can this fraction calculator handle mixed numbers?

Yes! Our fraction calculator fully supports mixed numbers like 2 3/4 or 5 1/2. Simply enter the whole number and fraction separately. The tool converts mixed numbers to improper fractions, performs the operation, and converts back if needed.

Free Fraction Calculator Online — Add, Subtract, Multiply & Divide Fractions 2026

Whether you're a student solving math homework, a chef scaling a recipe, a financial analyst working with ratios, or a professional dealing with measurements, our free fraction calculator online handles everything with instant, step-by-step precision. No app to download, no account to create — just open, enter, and calculate.

This tool supports all four fraction operations: addition, subtraction, multiplication, and division. It also handles mixed numbers (like 2 ¾), automatically simplifies results to lowest terms, converts to decimals and percentages, and shows the complete working so you actually understand the math.

How to Add Fractions with Different Denominators

Adding fractions with unlike denominators is a very common challenge in schools across the US, UK, Canada, and Australia. The correct method is to find the Least Common Denominator (LCD) — the smallest number that both denominators divide into — then convert each fraction to that denominator before adding numerators.

a/b + c/d = (a×d + c×b) / (b×d) → then simplify by GCD

Example: 1/3 + 1/4
LCD = 12 → 4/12 + 3/12 = 7/12 ✓

How to Subtract Fractions Online

Subtracting fractions follows the exact same logic as addition — find the LCD, convert, then subtract the numerators. The key step many people miss is simplification at the end. Our calculator always simplifies the result and shows you exactly how it was done.

a/b − c/d = (a×d − c×b) / (b×d) → then simplify by GCD

Example: 3/4 − 1/6
LCD = 12 → 9/12 − 2/12 = 7/12 ✓

Multiplying Fractions — Step by Step

Multiplying fractions is actually the easiest of the four operations — no need to find a common denominator. Simply multiply the numerators together and the denominators together, then simplify. This is used extensively in probability, cooking ratios, and financial calculations.

a/b × c/d = (a×c) / (b×d) → then simplify

Example: 2/3 × 3/4 = 6/12 = 1/2 ✓

Dividing Fractions — The "Keep, Change, Flip" Method

Division of fractions uses the reciprocal method — keep the first fraction as is, change the division sign to multiplication, and flip (take the reciprocal of) the second fraction. This method works universally and is taught in the UK's GCSE curriculum, the US Common Core standards, and the Australian Curriculum.

a/b ÷ c/d = a/b × d/c = (a×d) / (b×c) → then simplify

Example: 5/6 ÷ 2/3 = 5/6 × 3/2 = 15/12 = 5/4 ✓

Frequently Asked Questions — Fraction Calculator

How do you add fractions with different denominators? +

To add fractions with different denominators, find the Least Common Denominator (LCD), convert each fraction so they share that denominator, then add the numerators and keep the LCD as the denominator. Finally, simplify by dividing by the GCD. For example: 1/3 + 1/4 — the LCD is 12, so 4/12 + 3/12 = 7/12. Our calculator shows every step clearly.

How do you multiply fractions step by step? +

Multiplying fractions is the simplest of the four operations: multiply numerator × numerator and denominator × denominator, then simplify. No need to find a common denominator. Example: 2/3 × 3/4 = (2×3)/(3×4) = 6/12 = 1/2. You can cross-cancel before multiplying to make numbers smaller.

How do you divide fractions — what is Keep, Change, Flip? +

"Keep, Change, Flip" (KCF) is the mnemonic for fraction division: Keep the first fraction unchanged, Change the ÷ to ×, and Flip the second fraction (take its reciprocal). Example: 2/3 ÷ 4/5 → Keep 2/3, Change to ×, Flip 4/5 to 5/4 → 2/3 × 5/4 = 10/12 = 5/6.

How do you simplify a fraction to its lowest terms? +

Find the Greatest Common Divisor (GCD) of the numerator and denominator using the Euclidean algorithm, then divide both by the GCD. Example: 12/18 — GCD(12,18)=6 → 12÷6 / 18÷6 = 2/3. A fraction is in lowest terms when GCD = 1.

How do you convert a fraction to a decimal or percentage? +

Divide the numerator by the denominator to get the decimal. For example, 3/4 = 3 ÷ 4 = 0.75. To convert to a percentage, multiply by 100: 0.75 × 100 = 75%. For repeating decimals like 1/3 = 0.333..., our calculator displays them rounded to 6 decimal places.

What is the best free fraction calculator online in 2026? +

FinanceKit Pro's fraction calculator is rated among the best free tools in 2026 because it: handles all 4 operations, supports mixed numbers, shows step-by-step solutions, converts to decimal and percentage, works on any device without sign-up, and loads in under 2 seconds. It's used in 150+ countries with no ads blocking the calculator.

Can this calculator handle mixed numbers like 2 3/4? +

Yes! Toggle the "Mixed Numbers" switch above the calculator. You'll see an extra input for the whole number. The calculator converts mixed numbers to improper fractions internally, performs the operation, and presents the result as both an improper fraction and a mixed number when applicable.

How do you subtract fractions with unlike denominators? +

Find the LCD of both denominators, convert each fraction to that LCD, subtract the numerators, and simplify. Example: 3/4 − 1/6 → LCD = 12 → 9/12 − 2/12 = 7/12. If the result would be negative (smaller fraction minus larger), the answer will have a negative numerator.
