Overview

Reduce an integer fraction to lowest terms and normalize a negative denominator.

Calculator simulation

Try the DuckieDai calculator screen

Follow the reviewed program prompts and calculation flow before downloading.

Simulation boundary: This preview uses a reviewed browser adapter. It does not execute the downloaded Python and does not prove TI-Python or calculator compatibility.

JavaScript is required for the optional browser simulation. Source viewing and downloading remain available without it.

Usage

Inputs

Integer numerator
Nonzero integer denominator

Outputs

Fraction in lowest terms

Units: Integers; no physical units.

Assumptions and limitations

Assumptions

Inputs represent a fraction.

Constraints

The denominator cannot be zero.

Known failures

Non-integer input is rejected by the calculator conversion.

Compatibility and review

Review status: Tested on a TI calculator
Tested on: Creator-owned TI-84 Plus CE Python calculator; exact .py transferred and launched individually
What happened: Passed: creator personally tested the exact Fraction Simplifier program on a TI 84 Plus CE Python calculator.
Dependencies: No imports
Suggested calculator name: FRCSIM — you can give it another valid, unique name when you transfer it
Desktop test cases: Not available for this interactive-only source

This exact source auto-launches an interactive calculator session, so compatibility evidence comes from the recorded physical-device review rather than an importable desktop fixture.

Transfer and launch

Confirm that your calculator is the Python-capable model named above. Check that its OS and Python App versions match the reviewed record.
Download the .py source above and verify its SHA-256 digest if your computer provides that option.
Use TI Connect CE to send the Python file to a compatible calculator. FRCSIM is a suggested name; you may choose another valid, unique calculator name.
Open the Python App, select the program, and check sample inputs before relying on other results.

Read the complete installation, launch, troubleshooting, and removal guide.

Availability does not mean a teacher, school, or exam permits this program. Follow the applicable rules.
