Best Answer

When the bottom number and the top number in one fraction (example 2/6) are both divisible by the same number.

(so for 2/6 it would be helpful to divide 2 by 2 and 6 by 2, which would leave you with 1/3)ma'am or sir that is right.im nila. math wiz.u can also butterfly

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 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.


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.

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.


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.


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


Simplify fractions by dividing out common factors of 7x11?

7 & 11 have no common factor: both are prime.


The answer you get when you multiply?

the result would be greater than both or more factors, except for when you multiply by 0, 1 or fractions.
