Cross multiplying is a way to solve an equation that involves a variable as part of two fractions set equal to each other. The variable is a placeholder for an unknown number or quantity, and cross-multiplying reduces the proportion to one simple equation, allowing you to solve for the variable in question We multiply by numbers on the top of fractions and divide by numbers on the bottom of fractions. This is because the line in a fraction means to divide by the number below it. Cross cancelling divides the number we are multiplying by and the number we are dividing by by the same amount
From the above examples, you've seen how to cross multiply fractions: Take the denominator of one fraction and multiply both sides of the equation by that value.

So as long as we multiply or divide both the top and the bottom of a fraction by the same number, it's just the same as multiplying or dividing by 1 and we won't change the value of the fraction. Multiplication example: Since we multiplied the fraction by 1 or 2/2, the value doesn't change. The two fractions have the same value and are equivalent Cross Multiplication - Techniques & Examples Before we can discuss the cross-multiplication process, let's remind ourselves about the parts of a fraction.

Since these two fractions or ratios are in proportions, we know that the cross product must be equal. Using the cross product, we get: 5 × 16 = x × 10 80 = 10x If you know your multiplication table you can quickly get the answer. If 10 × x = 80, then x should be 8 because 10 × 8 is 80. x = Often times, students are asked to solve proportions before they've learned how to solve rational equations, which can be a bit of a problem.If one hasn't yet learned about rational expressions (that is, polynomial fractions), then it will be necessary to get by with cross-multiplication.. To cross-multiply, we start with an equation in which two fractions are set equal to each other Shortcut: Cross-Canceling. Instead of reducing the fraction at the end of the problem, we can cross-cancel before we multiply.It's not required, but it'll save a few steps. Cross-canceling means that when we're multiplying fractions, we can reduce any numerator with any denominator. In this example, 5 and 10 can both be divided by 5, even though they're not in the same fraction Multiplying Fractions Three simple steps are required to multiply two fractions: Step 1: Multiply the numerators from each fraction by each other (the numbers on top). The result is the numerator of the answer. Step 2: Multiply the denominators of each fraction by each other (the numbers on the bottom). The result is the denominator of the answer You will have to multiply . 2 3. × . 4 4. . 1 4. × . 3 3) The equation is now: 8 12. −. 3 12 = 5 12. Multiplying Fractions: You can multiply both the numerators and denominators, whether they are common or not. Example: 3 5. × . 1 4 = 3 20. Multiplying Fractions: If you can, you . must reduce.
