Properties of Proportions. The four properties that follow are not difficult to justify algebraically, but the details will not be presented here. Property 1 (Means‐Extremes Property, or Cross‐Products Property): If a/b = c/d, then ad =bc . Conversely, if ad = bc ≠ 0, then and . Example 1: Find a if a /12 = 3/4 If you know that two objects are similar, you can use proportions and cross products to find the length of an unknown side. Let's find the length of side DF, labeled x. We read this proportion as: AC is to AB as DF is to DE. Now, substitute in the lengths of the sides. Take the cross product to get the equation Decimal Multiplication: Worksheet 1.1 Name Date Score 1 The cross-multiplication method is explained as follows. In the elementary algebra and elementary arithmetic, when there is an equation given between two fractions or two irrational numbers, we can cross-multiply the two for either simplifying the equation or finding out the values of the unknown variables Multiply each side of the equation by 12. The fractions are eliminated. Emphasize that each term must be multiplied by the LCD in order to have a balanced equation.
