About this calculator
Overview
Ratio Calculator evaluates Ratio for the math / arithmetic library. Primary input cue: First Number [required] — field id `a`. Method anchor: Ratio = a:b = (a ÷ GCD):(b ÷ GCD). Find GCD of both numbers, divide each by GCD to get simplified ratio.
When to use
Appropriate when ratio is the target quantity and the form fields match your known data.
Inputs explained
- First Number [required] — field id `a`
- Second Number [required]
Formula / method
Ratio = a:b = (a ÷ GCD):(b ÷ GCD). Find GCD of both numbers, divide each by GCD to get simplified ratio (calculator id: ratio-calculator).
Worked example
Worked values: a = 12, b = 18 → a = 2, b = 3, ratio = 2:3
Interpreting results
Read the primary output as ratio under the method on this page.
Assumptions
- The wired execution function for `ratio-calculator` is the source of numerical behavior.
- Inputs for `ratio-calculator` follow the on-page labels; values/shapes must match this operation.
- Real-number arithmetic is used unless ratio explicitly needs integers.
Limitations
- Display rounding can differ slightly from a CAS/symbolic exact form of ratio.
- Edge cases outside the intended domain of ratio may error or look unstable—treat them as out of scope.
- Complex/branch cuts and undefined points are not always interactively annotated for ratio.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
