To find proportions in math, you can set up a proportion as an equation that states two ratios are equal. For example, if you have two ratios (a/b = c/d), you can cross-multiply to solve for an unknown: (a \cdot d = b \cdot c). You can also find proportions by dividing one quantity by another to determine their relationship, often expressed as a fraction or percentage. This is useful in various applications, such as scaling recipes or comparing quantities.
