When subtracting one fraction to another, one or both fractions are renamed so that they have the same denominators. Then the result of the subtraction is the equal to the subtraction of the numerators divided by the common denominator.

Finding the lowest common denominator
First you find a common multiple of the denominators. The least common denominator is handy but not essential. This number will be the denominator of the answer - before simplification.For both fractions find an equivalent fraction whose denominator is this common denominator.Carry out the subtraction on the new numerators to give the numerator of the answer.Simplify the result for the final, simplified answer.First you find a common multiple of the denominators.

The LCM is used for integers, not fractions. If you're trying to add unlike fractions, take the LCM of the denominators (known in this case as the least common denominator, or LCD), convert the fractions and proceed.
GCF doesn't apply to fractions, only to whole numbers. When those numbers are the numerator and denominator of a fraction, the GCF can be used to reduce it to its simplest form.
Finding the LCM will make adding and subtracting fractions easier.
Yes.
Answer: When adding or subtracting fractions with different denominators it is important to change the denominators into the lowest common denominator by using equivalent fractions. Answer: Equivalent fractions are used to: * Simplify fractions. It is sort of inelegant to write the final solution of a problem as 123/246, when you can just as well write it as 1/2. * Add fractions. If two fractions have different denominators, you need to convert them to equivalent fractions that have the same denominator. Only then can you add. * Subtract fractions (same as addition). * Compare fractions, to check which one is larger (same as addition).
It helps with the adding and subtracting of fractions.
A calculator is used for adding, subtracting, dividing, multiplying, decimals, or fractions and is also used for a lot of other uses too.
When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.
Anything having to do with adding or subtracting unlike fractions.
When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.
Fractions that are not equivalent are dissimilar fractions * * * * * The term is used more commonly to refer to fractions whose denominators are different.
GCF is used for factoring terms, possibly in solving equations. LCM is used to find a common denominator when adding or subtracting fractions.
When adding or subtracting fractions with different denominators then the least common multiple amongst them is needed to find the lowest common denominator.
