🔢 Fraction calculator with detailed solution

Adding, subtracting, multiplying, and dividing fractions is a foundation of math that often poses challenges in 5th and 6th grade. Our tool not only gives a ready-made answer, but also describes each step: search for a common denominator (NOK), additional factors, reduction and selection of the whole part.

🚀 How to use the calculator:

  1. Enter a fraction: Fill in the numerator (top field) and denominator (bottom field).
  2. Mixed number: If you have an integer part (for example, 2.56), enter "2" in the left box. For ordinary fractions, leave it blank.
  3. Select an action: Plus (➕), Minus (➖), Multiply (✖️) or Divide (➗).
  4. Get the solution: Click “Calculate” and see the entire solution progress.

📚 Cheat sheet: How to solve fractions by hand?

If you don't have a calculator at hand, use these rules. We use them in our algorithm.

➕ Addition and Subtraction

The main rule: The denominators must be equal!

  • Find the LCM (Least Common Multiple) of the denominators.
  • Adjust the numerators by additional factors.
  • Add (or subtract) the numerators, but leave the denominator the same.
1/2 + 1/3 = 3/6 + 2/6 = 5/6

✖️ Multiplication and Division

The common denominator is not needed.

  • Multiplication: Numerator × Numerator, Denominator × Denominator.
  • Division: The second fraction must be “reversed” (reversed) and the division sign replaced by multiplication.
2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12 = 5/6

Types of fractions we count

Our online tool works with all types of rational numbers:

  • Proper fractions:The numerator is less than the denominator (example: 3/4).
  • Improper fractions: The numerator is greater than the denominator (example: 5/2). The calculator will automatically highlight the whole part in the answer.
  • Mixed numbers: Whole number + fraction (example: 1 1/2). When making calculations, we convert them to improper fractions.

Frequently asked questions (FAQ)

🔹 How to enter a mixed fraction (with an integer number)?

The calculator interface has three fields for each fraction.

The first field (large) is for the whole part.

Second and third - for the numerator and denominator.

If you have a fraction without a whole part (for example, 2/5), simply leave the first field blank.

🔹 Does the calculator shorten the answer?
Yes, this happens automatically. For example, if the result of the calculation is 4/8, the system will find GCD (greatest common divisor - 4) and give a short answer: 1/2.
🔹 How to convert a fraction to a decimal?

Any fraction can be converted to a decimal by simply dividing the numerator by the denominator.

Example: 1/2 = 1 ÷ 2 = 0.5.

🔹 What to do if the denominators are different?
Nothing! Just enter the fractions as is. The program itself will find a common denominator, multiply the numerators and perform addition or subtraction. The entire process will be shown in the "Solution" block.
