How is a proportion changed into a mathematical equation?
a proportion is an equation. a / b = c / d cross multiply: ad = bc then solve
How do you solve proportions using cross products?
say it is 1 over 2 is equal to x over 4 you multiply 4 and 1 then 2 and x and you get 4=2x. Solve for x = 2. So the equivalent proportion is 2/4.
How do you cross products to solve proportion?
Let's say that the problem is x/2 = 3/6. You could begin to solve for x by cross-multiplying, which means that you would multiply each fraction's numerator by the other fraction's denominator and then you would set those products equal to each other. So in this case, you would have x · 6 = 3 · 2 after cross-multiplying. It can be proven that cross-multiplication is reliable: Let a/b = c/d a/b · d = c | multiply both sides by d ad/b = c | simplify ad = cb | multiply both sides by b

How To Solve A Proportion?
To solve a proportion, you cross multiply. For example, if this was the proportion: 2/4 = 3/x, you would multiply 2 with x and 4 with 3. The products will be used in your next equation. In this case, your next equation is 2x = 12. Now you want to isolate x, so divide by two for both sides. Your answer will be x = 6.
