Example: 30/42

Factor them.

2 x 3 x 5 = 30

2 x 3 x 7 = 42

Select the common factors.

2 x 3 = 6, the GCF

How would you take 8 percent make it a fraction with denominator of 100 and than break that down into a fraction in simplest terms?

You write 8 over 100: 8/100. To simplify, look for a common factor between the numerator and the denominator. If you find any, divide numerator and denominator by the common factor. Repeat, until you find no more common factors.You write 8 over 100: 8/100. To simplify, look for a common factor between the numerator and the denominator.

How to simplify fractions?

Find the Greatest Common Factor of the numerator and denominator, then divide the numerator by the GCF, and that is the new numerator. Divide the denominator by the GCF, and that is the new denominator.


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.


How do you find the lowest terms in fractions?

You look for common factors in numerator and denominator. If you find one, you divide both numerator and denominator by the common factor. For example, 8/14 has the common factor 2; if you divide top and bottom by 2, you get 6/7.


How do you find a fraction in simplest form?

You check whether the numerator and the denominator have a common factor. If they do, divide both the numerator and the denominator by this common factor. Continue until there are no more common factors. The greatest common factor can be found by prime factorization; for larger numbers, Euclid's algorithm is much more efficient.

How to simplify fractions?

Find the Greatest Common Factor of the numerator and denominator, then divide the numerator by the GCF, and that is the new numerator. Divide the denominator by the GCF, and that is the new denominator.


How do you find the least common factor to simplify?

find the lowest factor that equals the numerator and denominator.


How do you do simplest form?

how to find simplest form is: 1. Find the GCF of the numerator and denominator 2. Divide the numerator and denominator by the GCF


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 make fractions into simplest form?

-- Find any common factor of the numerator and denominator, and divide numerator and denominator by it. -- Keep doing that until the numerator and denominator no longer have any common factor except ' 1 '. The fraction is then in its simplest form.


How do you put the 40 over 100 in simplest form?

Find a common factor of the numerator and denominator and divide both by that common factor. Repeat with the resulting numerator and denominator until the common factor is 1. Alternatively, find the highest common factor (HCF) and divide both by the HCF.

How do you reduce a number?

first:you find the gcm(greatest common factor)wich is the lowest number that can go evenly into the numerator and the denominator. next:you devide both the numerator and the denominator by that gcm(greatest common factor)and walla!


What should you do to find a fractions simplest form and only have to divide once?

You have to find the greatest common factor between the numerator and the denominator. Then you divide numerator and denominator by this greatest common factor. There are several methods to find the greatest common factor. Note that "dividing only once" is not necessarily to your advantage; it is easier to divide by ANY common factor you find, and then continue looking for additional factors.
