A common denominator.
The best way is to find the LCM (Lowest Common Multiple) of all the denominators - the smallest number into which all the denominators will divide.
(The easiest way to do this is to multiply all the different denominators together.
Once this common denominator has been found, convert all the fractions into equivalent fractions with this new denominator.

What are the steps to subtract unlike fractions?
first find a common denominator then subtract the top numbers
Do you have to find a common denominator to subtract fractions?
Yes.
How do you minnous fractions?
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

When you subtract fractions do you subtract the denominator?
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
How do you find the difference of two fractions with the same denominator?
Subtract as if there were no denominators.
What are the steps to subtract unlike fractions?
first find a common denominator then subtract the top numbers
When you add or subtract fractions with unlike denominators why do you have to find LCM?
Because to add fractions, the denominators must be equal.
Why is it important to find the LCM of 2 numbers?
It will help when you want to add and subtract unlike fractions.
How do you subtract Fractions with models unlike denominators?
The denominators need to be the same for subtraction. Find the Least Common Denominator for both items and then subtract.
What can you find in order to add or subtract unlike fractions?
the common denominator. example: 3/4 times 2/3= 9/12 times 8/12= that ya go!
How can the greatest common factor and least common multiple help you work with fractions?
Finding the GCF of the numerator and the denominator of a fraction and dividing them both by it will give you the simplest form of that fraction. Finding the LCM of unlike denominators and converting them to it will make it possible to add and subtract unlike fractions.
How do you subtract unlike fractions?
The first thing you obviously do is find an equivalent fraction for thedenominator number at the bottom of the fraction.).After you've done that you gotta subtract whatever you put to the top you put to the bottom! :>
What does find the common denominator for the fraction pairs mean?
It means find the LCM of the denominators. In order to add and subtract fractions with unlike denominators, it is necessary to convert them to equivalent fractions with a common denominator. Example: 1/4 + 1/6 The LCM of 4 and 6 is 12. 1/4 = 3/12 1/6 = 2/12
Do you have to find a common denominator to subtract fractions?
Yes.
How do you subtract two fractions?
You have to find a common denominator, multiply them, subtract them and then simplify if you need to.
