How to Use the Ratio Simplifier & Proportion Solver
-
1
Mode 1 (Simplify): Enter two or three numbers (e.g. 24:36) to reduce them to lowest common terms (e.g. 2:3).
-
2
Mode 2 (Solve Proportion): Enter three known values in $A/B = C/X$ to cross-multiply and solve for $X$.
-
3
Mode 3 (Divide Total): Enter a total dollar or unit amount and a ratio (e.g. $1,000 in 3:5:2) to compute each proportional share.
Practical Example & Use Case
Solving an aspect ratio: if a 1920x1080 video is scaled to width 1280, the proportion solver finds the height is 720 (16:9 ratio).
Technical Notes & Limitations
Calculates exact fractional and integer GCD reductions.
Frequently Asked Questions
How do you solve a proportion equation?
By cross-multiplying: in $A/B = C/X$, $A \times X = B \times C$, so $X = (B \times C) / A$.
