A proportion is two fractions A proportion is two fractions 2 x 10 5 A proportion is two fractions two fractions 2 x 10 5 A proportion is two fractions separated by an equal sign 2 x 10 5 A proportion is two fractions separated by an equal sign 2 x = 10 5 A proportion is two fractions separated by an equal sign 2 x = equal sign 10 5 To solve a proportion To solve a proportion 2 x = 10 5 To solve a proportion we use cross multiplication 2 x = 10 5 To solve a proportion First multiply one diagonal we use cross multiplication 2 x = 10 5 To solve a proportion First multiply one diagonal we use cross multiplication 2 x = 10 5 To solve a proportion First multiply one diagonal we use cross multiplication 2 x 10x = 10 5 To solve a proportion First multiply one diagonal we use cross multiplication then multiply the second diagonal 2 x 10x = 10 5 To solve a proportion First multiply one diagonal we use cross multiplication then multiply the second diagonal 2 x 10x = 10 5 To solve a proportion First multiply one diagonal we use cross multiplication then multiply the second diagonal finally put an equal sign in between them 2 x 10x = 10 10 5 To solve a proportion First multiply one diagonal we use cross multiplication then multiply the second diagonal finally put an equal sign in between them 2 x 10x = = 10 10 5 To solve a proportion First multiply one diagonal we use cross multiplication then multiply the second diagonal finally put an equal sign in between them 2 x 10x = = 10 10 5 then solve the equation To solve a proportion First multiply one diagonal we use cross multiplication then multiply the second diagonal finally put an equal sign in between them 2 x 10x = = 10 10 5 then solve the equation x = 1 Which equation is the result of cross multiplication 5 x 5x = 240 20x = 60 12x = 100 = 20 12 5 x x = = 20 12 If the proportion contains a binomial If the proportion contains a binomial x - 3 4 = 3 2 If the proportion contains a binomial x - 3 4 = proportion 3 2 If the proportion contains a binomial x - 3 4 = binomial 3 2 If the proportion contains a binomial cross multiplication will involve parenthesis x - 3 4 = 3 2 If the proportion contains a binomial cross multiplication will involve parenthesis x - 3 4 = 3 2 If the proportion contains a binomial cross multiplication will involve parenthesis 2(x - 3) x - 3 4 = 3 2 If the proportion contains a binomial cross multiplication will involve parenthesis 2(x - 3) x - 3 4 = 3 2 If the proportion contains a binomial cross multiplication will involve parenthesis 2(x - 3) x - 3 4 12 = 3 2 If the proportion contains a binomial cross multiplication will involve parenthesis 2(x - 3) x - 3 4 = 12 = 3 2 If the proportion contains a binomial cross multiplication will involve parenthesis 2x - 6 = 12 2(x - 3) x - 3 4 = 12 = 3 2 If the proportion contains a binomial cross multiplication will involve parenthesis 2x - 6 = 12 2(x - 3) 2x = 18 x - 3 4 = 12 = 3 2 If the proportion contains a binomial cross multiplication will involve parenthesis 2x - 6 = 12 2(x - 3) 2x = 18 x = 9 x - 3 4 = 12 = 3 2 Which equation come from cross multiplication? x + 5 3 3(x + 5) = 84 7(x + 5) = 36 12(x + 5) = 21 = 12 7 |
