To simplify a multiplication or division involving fractions, you need to find common factors. For small numbers, you might just try to do a complete factorization of each of the numbers involved. It's best not to multiply them in the first place; it doesn't really make sense to multiply and then factorize again. For larger numbers, you can use Euclid's algorithm to find the greatest common factor.

To divide one fraction by another, you don't need a "common factor".
You simply multiply the first fraction, by the reciprocal of the second fraction.
Finding a common denominator is required for addition, subtraction, or comparison (i.e., finding out which fraction is greater).

How to use division to find equivalent fractions?
You divide top and bottom by the same number, if you find a common factor. For example, if your fraction is 9/12, you check whether top and bottom have any common factor greater than one (in this case, the common factor is 3), and then you divide top and bottom by 3, to get 3/4.
How do you find out if a fraction is in its simplest form?
You find the highest common factor of the numerator and denominator. If that is 1, then the fraction is in its simplest form.
How do you FIND a fraction when it is in simplest form?
A fraction is in simplest form when the numerator and denominator have no common factor except ' 1 '.
How is gcf used to find the simplest form of a fraction?
To simplify a fraction, the numerator and denominator are divided by a common factor. The simplification process is continued until there is no common factor. By dividing the numerator and denominator by their greatest common factor no further simplification is possible.
What are the rules for the simplest form of fraction?
Divide the numerator and denominator by their highest common factor to find the simplest form of a fraction

How do you find the least common factor in division?
The least common factor is always 1.
What is 28 of 100 into a fraction?
It is simply 28/100.You can find equivalent fractions if you multiply the numerator and denominator of this ratio by any non-zero integer. Or you could divided them both by a common factor. Division by the highest common factor will give the simplest form of the rational fraction.
How can the greatest common factor help you write a fraction in simplest form?
Find the greatest common factor between the numerator and the denominator, then divide the numerator by greatest common factor and then divide denominator by greatest common factor, for a new simplified fraction.
How do you find out if a fraction is in its simplest form?
You find the highest common factor of the numerator and denominator. If that is 1, then the fraction is in its simplest form.
How do you write a fraction in its simplest term?
find the greatest common factor divide by it then you have an answer
What fraction is equivalent to eight twelves?
See if you can find a common factor between the two numbers. Then divide top and bottom of the fraction by this common factor.
How do you change fraction in lowest term?
Find the highest common factor of the numerator and the denominator and divide the factor into both of them to change the fraction into its lowest terms.
Fraction into simplest form?
you find the GCF (GREATEST COMMON FACTOR) then you divide or multiply you can pick and then you get you simplest from of the fraction
