About this calculator
A ratio compares relative sizes; simplification strips common factors so 6:18 reads plainly as 1:3. Ratios power recipes, concrete mixes, screen resolutions and financial leverage alike.
Formula
Divide both parts by their GCD to simplify. Shares = total × part/(part₁+part₂).
Frequently Asked Questions
Is 3:4 the same as 4:3?
No — order matters. 3:4 means 3 parts of the first for every 4 of the second; reversed it's a different relationship (0.75 vs 1.33).
Non-integer ratios?
GCD simplification applies to whole numbers only; decimals display scaled to the smaller part instead.
