How to use the Ratio Calculator
Estimate greatest common divisor from first term, second term with the Ratio Calculator. It includes Simplify Ratio, Ratio Scaling workflows, so choose the one that matches the values you actually know. Use it to check the arithmetic while keeping the displayed method and entered values with your work.
Step by step
- For the Ratio example, select Simplify Ratio and enter first term, second term. Keep each value in the unit displayed beside its field.
- Review the selected Ratio workflow and inputs, then read greatest common divisor in the result panel.
- Change one Ratio assumption at a time to compare scenarios. Use Reset to restore this tool's worked example values.
How the calculation works
Reduces an integer ratio or scales both terms by a common factor.
Worked example
To reproduce the Ratio worked example, reset the calculator. Select the Simplify Ratio workflow. Use first term 1,920; second term 1,080. The result is greatest common divisor of 120. Simplify Ratio: Reduces an integer ratio or scales both terms by a common factor. Review the displayed units before comparing the result.
Understanding the result
The Ratio reports greatest common divisor. Use it to check the arithmetic while keeping the displayed method and entered values with your work. The result depends on the entered values, selected mode, and displayed mathematical assumptions.
How to check the answer
Check the Ratio answer by substituting greatest common divisor back into the stated relationship. Test a simple value such as zero, one, or an equal pair, then confirm that sign, scale, units, and rounding match Reduces an integer ratio or scales both terms by a common factor.
Common questions
What does the Ratio calculate?
Estimate greatest common divisor from first term, second term with the Ratio Calculator.
Which inputs does the Ratio example use?
The worked example uses first term, second term in the Simplify Ratio workflow. Other workflows can show different fields. Keep the chosen workflow and units with the result when comparing calculations.
Is the Ratio result exact?
The result depends on the entered values, selected mode, and displayed mathematical assumptions. Recheck first term, second term and use greatest common divisor only for a decision where that level of precision is appropriate.
