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.

How are equivalent fractions used in renaming when subtracting?
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.
How do you find the LCM multiple for two fractions?
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.
what is a reference point that is used for estimating fractions?
benchmark fractions
What is used in changing dissimilar fractions to similar fractions?
Finding the lowest common denominator
Why is LCM important?
The LCM is used to convert unlike rational fraction to like fractions so that they can be added or subtracted. Any common multiple will do so the LCM is not that important. However, using the LCM will ensure that the numbers that you have to deal with are as small as they can be.
What problems can be solved using gcf and LCM?
Finding the LCM will make adding and subtracting fractions easier.
What is the use of LCM?
When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.
What type of problems can be used using the least common multiple?
Anything having to do with adding or subtracting unlike fractions.
How you use the least common multiple?
When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.

Is Least Common Denominator used for subtracting fractions?
Yes.
What is the least common multiple used for?
It helps with the adding and subtracting of fractions.
Why is it important to learn about equivalent fractions?
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).
What is a calculater used for?
A calculator is used for adding, subtracting, dividing, multiplying, decimals, or fractions and is also used for a lot of other uses too.
How are equivalent fractions used when adding unlike fractions?
If you need to add 1/3 and 1/4, both can be converted into equivalent fractions using 12 as the common denominator. 1/3 is multiplied by 4/4 to get 4/12. 1/4 is multiplied by 3/3 to get 3/12. Add them, 4/12 + 3/12 = 7/12.

What is the meaning of disimilar fraction?
Fractions that are not equivalent are dissimilar fractions * * * * * The term is used more commonly to refer to fractions whose denominators are different.
