How to use the fraction calculator
Tap Add, Subtract, Multiply, or Divide, then type whole numbers in the two boxes (like 2 and 3). Fractions such as 1/2 work too. The answer appears on the right.
Rules at a glance
Add/subtract: common denominator, then combine numerators. Multiply: multiply numerators and denominators. Divide: multiply by the reciprocal.
Example: 2 + 3
Pick Add, enter 2 and 3 → 5.
Mixed numbers and homework checks
Enter whole parts with a space before the fraction (1 3/4). Results reduce when possible so 2/4 becomes 1/2. Decimals help compare to calculator-style answers.
Example: splitting a pizza
You eat 3/8 of a pizza and your friend eats 2/8 → add 3/8 + 2/8 = 5/8 gone.
Example: recipe scaling
Recipe needs 3/4 cup flour; double it → multiply 3/4 × 2 = 3/2 = 1 1/2 cups.
How do you add fractions?
For whole numbers, add like usual—enter 2 and 3 with Add to get 5. For fractions, enter values like 1/2 and 1/3 and the calculator handles common denominators.
What is 2 plus 3?
2 + 3 = 5. Choose Add and type 2 and 3 in the two boxes.
How do you multiply fractions?
Multiply numerators together and denominators together, then simplify. Choose Multiply and type both fractions.
How do you divide fractions?

How do you subtract fractions?
Find a common denominator, subtract numerators, simplify. Choose Subtract and enter both values.
What is 3/4 plus 1/4?
3/4 + 1/4 = 1. Enter 3/4 and 1/4 with Add—the answer simplifies to 1.
How do you simplify a fraction?
Divide numerator and denominator by their greatest common divisor. This calculator simplifies automatically in the result box.
How do you type a mixed number?
Use a space between the whole part and fraction, like 1 1/2 for one and a half.
