How to use the ratio calculator
Enter the two values in the order you want them compared. For whole numbers, the calculator divides both by their greatest common divisor.
Ratio simplification
Order matters. A ratio of 2:3 does not mean the same thing as 3:2.
Example: Sofia simplifies a mixture ratio
Sofia mixes 16 parts of one ingredient with 24 parts of another. Both values divide by 8, so the simplified ratio is 2:3.
This means two parts of the first ingredient for every three parts of the second. The total is five parts; the first ingredient is 2/5 of the mixture, not 2/3.
Use equivalent whole-number quantities
The ratio 12:18 simplifies to 2:3 because both values divide by 6. Keep the quantities in matching units before simplifying.
For decimal quantities, multiply both sides by the same power of ten first. For example, 1.5:2.5 becomes 15:25, then 3:5.
Simplify quantities after matching their units
A ratio of 2 meters to 50 centimeters is 200:50 after converting both lengths to centimeters. Dividing both parts by 50 gives 4:1. Entering 2:50 directly would compare unmatched units.
This tool simplifies whole-number parts. To express 1.5:2.5, multiply both parts by 10 first and enter 15:25, which simplifies to 3:5. Keep the order of the quantities unchanged.
Assumptions and limitations
What the estimate assumes
The simplification result is designed primarily for integer inputs.
Ratio Calculator FAQs
How do I simplify a ratio?
Divide both sides by their greatest common divisor.
Does ratio order matter?
Yes. 2:3 and 3:2 describe different relationships.
Can a ratio include zero?
One side can be zero, but a decimal A ÷ B is undefined when the second value is zero.
Is a ratio the same as a fraction?
They can represent the same division relationship, but ratios are often written with a colon to compare quantities.
