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.

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 is the least common multiple used when adding and subtracting fractions?

When adding and subtracting unlike fractions, find the LCM of the denominators and convert them to it. In this case, it's called the least common denominator, but it's the same process.


How you use the least common multiple?

When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.


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.


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).


How is the LCM used in everyday life?

When adding or subtracting fractions with different denominators the LCD is found with the LCM.


What types of problems can be solved using the GCF and LCM?

The GCF can be used to reduce fractions. The LCM can be used to add and subtract unlike fractions.


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 do you know when to use common factors or common multiples to solve a problem?

When reducing fractions to their lowest terms the HCF is used When adding or subtracting fractions with different denominators the LCM is used


How are lcm's used in adding or subtracting fractions?

To add and subtract fractions, you need common denominators. To find the common denominator, take the LCM of the denominators you wish to add or subtract.


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.


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.


When would you apply gcf instead of lcm?

GCF is used for factoring terms, possibly in solving equations. LCM is used to find a common denominator when adding or subtracting fractions.

What is least common multiple used for?

When adding or subtracting fractions with different denominators then the least common multiple amongst them is needed to find the lowest common denominator.


Where are fractions used?

What is a sentence for least common multiple?

The least common multiple of 6 and 9 is 18.


In how many different ways can you add 2 over 3 and 5 over 6?

There is only one way - make then into equivalent fractions with the same denominator and then add the numerators and simplify if possible. However, there are infinitely many equivalent fractions that can be used - all multiples of the lowest common multiple of 3 and 6 (which is 6) can be used as the denominator for the equivalent fractions.

You're only supposed to ask one question at at time but here we go:- 1 Fractions are parts of whole numbers or integers 2 Fractions less than 1 are common fractions 3 Fractions greater than 1 are improper fractions 4 Fractions have denominators which are underneath their numerators 5 Fractions are separated by a solidus line such as n/d 6 Fractions that are improper can be changed into mixed numbers 7 Fractions can be changed into decimals 8 Fractions can be converted into percentages 9 Fractions are rational numbers 10 Fractions can not be derived from irrational numbers 11 Fractions need a LCD when adding or subtracting them 12 Fractions can be easily multiplied and divided 13 Fractions can be equivalent such as 2/3 = 4/6 14 Fractions can be simplified by finding their HCF 15 Fractions use prime numbers to find the LCM of different denominators 16 Fractions were once used by the ancient Romans to a limited extent


Find the LCD then add or subtract?

To add or subtract fractions the denominators must be the same - then the numerators are added or subtracted with the denominator being kept the same.When adding or subtracting fractions with different denominators, the fractions must first be converted into equivalent fractions with the same denominator and then the (new) numerators can be added or subtracted as required.For the denominator for these equivalent fractions, the original denominators can all be multiplied together, but this can lead to having to work with very large numbers; a better choice for the denominator is the smallest number that all the denominators divide into, their Least Common Multiple (LCM) - this is is then used as the denominator for the equivalent fractions and is called the Least Common Denominator (LCD) of the fractions.First you find the LCD okay??? Then you have to add or subtract. What they mean by that is that once you've found your lcd add or subtract..xx hope i helped :)


What is the difference between a least common multiple and a least common denominator?

The Least (or Lowest) Common Multiple (LCM) is the smallest number that is a multiple of both numbers. For example: the LCM of 10 and 4 is 20, because both 10 and 4 go into 20 and 20 is the smallest number both 10 and 4 can go into. To be able to add or subtract fractions they must have the same denominator. If the denominators are different then the fractions must first be converted into equivalent fractions with a common denominator; any common denominator can be used, but by using the Least Common Multiple of the denominators as the new denominator it keeps the numbers smaller; this smallest denominator is known as the Least Common Denominator Thus the Least Common Denominator is the Least Common Multiple of the denominators of two (or more) fractions (used when adding or subtracting fractions with different denominators). As the Least Common Multiple is used most often with adding or subtracting fractions, it is often referred to as the Least Common Denominator (because the numbers being considered are usually denominators of fractions).
