Mastering Proportions: Unlocking Equations With Cross-Multiplication And Equivalent Fractions
A proportion expresses the equality of two ratios, often denoted as a/b = c/d. Solving for a specific value of x in a proportion involves finding the value that makes the proportion true. This is done by cross-multiplication, where the cross-products between the numerators and denominators are equated, i.e., ad = bc. Alternatively, an equivalent…
