What else can I help you with?
How do you simplify expressions with variables?
You multiply out brackets, remove common factors from fractions, combine like terms.
How do you multiply fractions with variables?
In order to multiply fractions with variables, factor all numerators and denominators completely. Use the rules for multiplying and dividing fractions, cancel any common factors, and leave your final answer in factored form.
How does knowing factors help you simplify fractions?
Knowing factors will help you find a GCF. To simplify a fraction, divide the numerator and the denominator by their GCF.
What is cross canceling in dividing fractions?
Cross canceling in dividing fractions is when you simplify the fractions by canceling out common factors in the numerators and denominators diagonally across from each other. This helps to make the division process easier and quicker. So, basically, it's like cutting out the middleman and getting straight to the point when dividing fractions.
When multiplying proper fractions why is the product less than the both factors?
A proper fraction is less than 1. Any positive number multiplied by a positive number less 1 will be less than itself. In multiplying two proper fractions, each one is being multiplied by a number less than 1.
When you multiply fractions why do you multiply the fractions strait across?
This has the effect of producing a denominator in the answer that has each of the original denominators as factors. You don't have to worry about simplifying the fractions before multiplying. Of course, you may have to simplify after multiplying. There's no way out.
Do you have to change the denominators when multiplying fractions?
No. To multiple fractions multiple the numerators together and multiply the denominators together and simplify (by dividing both numerator and denominator of the result by common factors until the only common factor is 1). The denominators only need to be the same when adding or subtracting fractions.

How do you multiply fractions with variables?
In order to multiply fractions with variables, factor all numerators and denominators completely. Use the rules for multiplying and dividing fractions, cancel any common factors, and leave your final answer in factored form.
How do you simplify with complex fractions?
To simplify complex fractions, first rewrite the complex fraction as a division of two fractions. Identify the numerator and denominator, and if necessary, find a common denominator for the fractions involved. Then, multiply both the numerator and the denominator by that common denominator to eliminate the fractions. Finally, simplify the resulting expression by reducing any common factors.
How are common factors useful?
They are useful in reducing fractions and to simplify radicals. They are useful in reducing fractions and to simplify radicals.
When multiplying use fraction notification we form products in the numerator and the denominator but do not immediatily calculate the product?
That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.
What is the rule for multiplying fractions with like denamonators?
Multiply all numerators to get numerator of the product. Multiply all denominators to get denominator of the product. This is true whether the factors have like or unlike denominators.
How does knowing factors help you simplify fractions?
Knowing factors will help you find a GCF. To simplify a fraction, divide the numerator and the denominator by their GCF.
What is cross cancelling when you times fractions?
Cross cancelling is a simplification method used when multiplying fractions. It involves reducing the numerators and denominators across the fractions before performing the multiplication. By dividing common factors, you can simplify the calculation, making it easier and quicker to find the product. For example, in the multiplication of ( \frac{a}{b} \times \frac{c}{d} ), if ( a ) and ( d ) share a common factor, you can divide both by that factor before multiplying the fractions.
When multiplying fractions you can divide out common factors so that the product will be in what?
simplest form
How do you multiiply fractions?
A fraction can be written as a numerator (top) over a denominator (bottom).To multiply two fractions youmultiply their numerators to get the numerator of the answer,multiply their denominators to get the denominator of the answer,simplify the answer to remove any common factors in the numerator and denominator.Thus:3/4 * 8/9 = (3*8)/(4*9) = 24/36 = 2/3
