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

You multiply out brackets, remove common factors from fractions, combine like terms.

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.

Knowing factors will help you find a GCF. To simplify a fraction, divide the numerator and the denominator by their GCF.

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.

57 has 4 factors (if you are multiplying). 1,3,19,57

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.

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.

That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.That is correct.

They are useful in reducing fractions and to simplify radicals. They are useful in reducing fractions and to simplify radicals.

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.

simplest form

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

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

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