How it is calculated
Turn the terms into whole numbers, then divide each by the greatest common divisor of all terms
Example
Inputs: First term = 12, Second term = 18. Result: Simplified ratio: 2:3; Share of term 1: 40%; Share of term 2: 60%.
Limits and caveats
- Terms must be positive, and the 1:n form is rounded to 4 decimal places.
- Takes up to 3 terms.
Questions about this tool
How do I simplify 12:18?
The greatest common divisor is 6. Divide both terms by 6 to get 2:3.
How do I simplify a ratio with decimals?
Multiply the terms by 10 or 100 until they are whole, then simplify. 1.5:2.5 becomes 15:25 and then 3:5.
What does the share of each term mean?
It is each term as a percentage of the total. In 2:3 the first part is 40% and the second is 60%.
