Formula and methodology
Formula: a/b = c/x; x = bc/a; ratio decimal = a/b = c/x.
Cross multiplication turns the proportion into ax = bc, so the unknown denominator is bc divided by a. The ratio value and cross-product check make the result transparent.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- First ratio numerator a — minimum 1.0E-6; maximum 1000000000
- First ratio denominator b — minimum 1.0E-6; maximum 1000000000
- Second ratio numerator c — minimum 1.0E-6; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| First ratio numerator a | 2 |
| First ratio denominator b | 3 |
| Second ratio numerator c | 8 |
Missing denominator: 12; both ratios equal about 0.6667.
Assumptions and limits
- All three entered quantities are positive and use compatible ratio units.
- The missing value is the denominator of the second ratio, not a percentage or a unit conversion.
- A ratio is dimensionless only when numerator and denominator share compatible units.
