Fraction Calculator — Complete Guide & Instructions
MakeCard Fraction Calculator performs all four operations on two fractions and reduces the answer to its simplest form automatically. Enter numerators and denominators, pick +, −, ×, or ÷, and the result appears as a simplified fraction plus its decimal and mixed-number equivalents. It is built for students checking homework and anyone who needs exact fraction math instead of decimal approximations.
How to Use Fraction Calculator

Pro Tips for Best Results
- Dividing by a fraction is the same as multiplying by its reciprocal — the tool handles it automatically.
- Watch the simplified output: 2/4 + 1/4 correctly reduces to 3/4.
- Use the mixed-number readout for recipes — 7/4 becomes 1 3/4.
Common Problems & Solutions
A zero in either denominator is undefined — check the bottom fields and enter non-zero values.
The tool always reduces by GCD; if it shows a large fraction, that is already the lowest form.
