Best Answer

Example: 1/15 x 9/2

In this case, you can cross simplify. No, it does not have to be simplified with whatever numbers are given. You just have to find the GCF which is 3 in this case.

Now you should have:

1/5 x 3/2 = 3/10.

To simplify a fraction, you find a number that can be divided by the fraction you are simplifying. sometimes this does not always work and the fraction can not be simplified.

How do you simplify when its just one number in fractions?

A fraction always has one number on top (the numerator), and another number on the bottom (the denominator). If it doesn't have both of those, then it's not a fraction.

How do you write each fractions as a mixed number in simplest form?

Divide the top number into the bottom number..when u get your ONE remainder (one you should only have one remainder don't keep going with the fraction or add a decimal) The top number is the big number to the side and the remainder is the numerator and the bottom is the dominater. And if it needs simplifying well simplify.


How can fractions be simplified by finding the GCF and using divisibility rules?

Simplifying fractions and finding the GCF is easy. All you have to do is put the fraction into simplest form and then put in a whole number.


Do you first simplify the number then make it a mixed number?

Mathematically, it does not matter which you do first. In practical terms, simplifying first is better because then you are doing subsequent calculation with smaller numbers.


What 2 or more numbers for a gcf represent?

The GCF is the largest whole number that is a factor for both of the numbers of interest. GCF is useful when simplifying fractions.


How do you multiply fractions into a whole number?

Multiply the numerator (top) of the fraction by the whole number to make the new numerator.The denominator (bottom) of the fraction of is the new denominator.Simplify, if required.For example, 2/9 * 6New numerator = 2*6 = 12New denominator = 9 so that the answer, before simplifying, is 12/9.Simplify 12/9 to 4/3.


What is a simplifie?

Simplify (not simplifie) has many meanings which depend on the context. In the context of ratios or fractions, it means reducing the ratio to its lowest or simplest form. This requires the numerator and denominator to be divided by their greatest common factor. If the fractions contain surds or complex numbers in the denominator, simplifying means removing these to the numerator. This requires multiplying both the numerator and denominator by the conjugate number. In the context of an equation or expression, it means to combine like terms.
