Understanding Proportions in Simple Words
A proportion shows that two ratios are equal to each other. It explains how one quantity changes in relation to another while keeping the same relationship. Proportions are commonly written in the form a:b = c:d. This concept helps in finding missing values, comparing quantities, and maintaining balance between numbers in real-life situations.

How the Proportion Calculator Solves Equations
The calculator uses cross multiplication, a standard mathematical method. When three values are known, it multiplies across the equation and divides to find the missing term.
Strong Example:
If 3/6 = x/12 → x = (3 × 12) ÷ 6 =
6
This proportion solver completes calculations instantly without manual effort.
