Ratio to Fraction Converter
Transform any ratio into a clear fraction. This tool calculates the 'part-to-whole' relationship, making it easy to understand proportions in probability, cooking, and finance.
How do you convert a ratio to a fraction?
To convert a "part-to-part" ratio (A:B) to a fraction, the numerator is A and the denominator is the sum of both parts (A + B). For example, a ratio of 1:3 becomes the fraction 1/(1+3) = 1/4.
What is the difference between part-to-part and part-to-whole ratios?
A part-to-part ratio compares two individual parts (e.g., 2 red balls to 3 blue balls). A part-to-whole ratio compares one part to the entire set (e.g., 2 red balls to 5 total balls). Fractions are naturally part-to-whole.
How do I convert a 3-part ratio to fractions?
For a ratio A:B:C, you can create three fractions: A/(A+B+C), B/(A+B+C), and C/(A+B+C). These fractions represent the proportion of the total that each part occupies.
Can a ratio be a fraction directly?
Only if it is a "part-to-whole" ratio. In that case, the ratio 3:4 means 3 out of every 4, which is the same as the fraction 3/4.
