Calculator Form
Large screens show three columns, smaller screens show two, and mobile shows one. For “Improper to Mixed,” enter the improper numerator in the first numerator field, keep the denominator in the first denominator field, and ignore the whole number.
Example Data Table
| Mode | Input A | Input B | Fraction Result | Mixed Result | Decimal |
|---|---|---|---|---|---|
| Add | 2 1/3 | 1 3/4 | 49/12 | 4 1/12 | 4.08333333 |
| Subtract | 5 2/5 | 1 1/10 | 43/10 | 4 3/10 | 4.3 |
| Multiply | 1 2/3 | 2 1/4 | 15/4 | 3 3/4 | 3.75 |
| Divide | 3 1/2 | 1 3/4 | 2 | 2 | 2 |
Formula Used
Mixed to improper: (whole × denominator + numerator) / denominator. Keep the sign of the mixed number.
Improper to mixed: divide numerator by denominator. The quotient becomes the whole number, and the remainder stays over the denominator.
Add or subtract: convert mixed numbers to improper fractions, find a common denominator, combine numerators, then simplify.
Multiply: convert both values to improper fractions, multiply numerators, multiply denominators, then reduce using the greatest common divisor.
Divide: convert to improper fractions, multiply the first fraction by the reciprocal of the second, then simplify the answer.
Compare: use cross multiplication, a/b ? c/d becomes a×d ? c×b, which avoids rounding errors.

Frequently Asked Questions
1. What is a mixed number?
A mixed number combines a whole number and a proper fraction, such as 3 1/2. It represents the same value as an improper fraction.
2. Why convert mixed numbers to improper fractions first?
Improper fractions make addition, subtraction, multiplication, and division more consistent. They let you work with one numerator and one denominator per value.
3. Can this calculator compare two mixed numbers exactly?
Yes. It compares values through fraction logic and cross multiplication, which avoids decimal rounding differences that can affect close results.
4. How are negative mixed numbers handled?
Enter the negative sign in the whole number field, such as -2 with 1/3. The calculator treats the full mixed number as negative.
5. What happens if the denominator is zero?
The calculator blocks the calculation and shows an error message because division by zero makes a fraction undefined.
6. When should I use the improper-to-mixed mode?
Use it when you already have a top-heavy fraction, such as 17/5, and want the answer rewritten as a whole number plus a remainder fraction.
7. Does the calculator simplify answers automatically?
Yes. Results are reduced using the greatest common divisor, then shown in simplified fraction form and mixed-number form whenever applicable.
8. What do the CSV and PDF exports include?
CSV export stores the latest result fields as rows. PDF export captures the visible result summary and method steps for printing or sharing.
