FAQ
Questions people usually have.
What if one side is zero?
The calculator still runs, but a ratio with a zero side means all of the total goes to the other side.
Are decimals supported?
Inputs accept decimals, but simplification rounds to whole-number ratio parts. Use whole-number parts when you need exact simplification.
