Method & formula
Decimal terms are first converted to an equivalent integer pair, then reduced by their greatest common divisor. Percentage views are calculated separately and return Undefined when their denominator is zero.
- Simplified ratio = equivalent integer terms ÷ greatest common divisor
- First as % of second = first / second × 100
Example
8:12 simplifies to 2:3. The first term is 66.666…% of the second.
FAQ
Can I enter decimals?
Yes. Decimal terms are scaled to an exact integer pair before simplification.
What happens with a zero term?
A ratio such as 0:5 can be simplified, but any percentage that divides by zero is reported as Undefined. 0:0 is rejected.
