FractionSolver calculates fractions and mixed numbers with step-by-step working. It includes arithmetic, simplification, comparison, decimal and percentage conversion. Camera scanning, history and worked-solution image export are Premium features.
When to use it
Check how a common denominator or fraction reduction leads to an answer, rather than copying the final number.
Limits to check
The solver uses local deterministic rules, not a generative AI answer. OCR can misread handwriting; correct the input first. Decimal conversion can show repeating digits in parentheses.
Storage and connections
The official description states that calculation and camera OCR run on-device without an account or internet connection.
A practical workflow
-
Enter the expression with the math keypad, or use Premium camera scanning.
-
Check the recognized expression before calculating, especially signs and mixed numbers.
-
Follow the displayed steps and use the fraction diagrams to explain the result.
