If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator.

Not always but they need to have the same denominators when adding or subtracting them.


How do you minnous fractions?

To subtract fractions with like denominators, subtract the numerators , and write the difference over the denominator. Example : Find 45โˆ’25 . Since the denominators are the same, subtract the numerators.


When adding fractions with like denominators how do you convert?

When adding fractions with like denominators, add the numerators together and put the result over the denominator. Simplify if possible.


What way is subracting fractions with unlike denominators like adding fractions with unlike denominators?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.


Why does the equivalent fraction make adding and subtracting fractions easier?

You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent fractions.


Adding unlike fractions?

yes of coarse! only if you are adding fractions that is.


What is the secret to adding fractions?

When adding or subtacting fractions make sure that the denominators are of the same values if they are not then find the lowest common denominator.


how to rename fractions using LCM?

When adding or subtracting fractions with different denominators their lowest common denominator must be found first by using the LCM of their denominators


Do you find the GCF or LCM when adding fractions?

When adding fractions, you want to make sure that the denominators are the same. It's the same process as the LCM.

How do you subtract improper fractions with different denominators?

It's the same thing as adding or subtracting normal fractions - just make sure both fractions have the same denominators (by either multiplying the denominators or simplifying the fraction - whichever the question needs).


How do you check you math with adding fractions?

When adding or subtracting fractions first make sure that the denominators are the same if they aren't then find the lowest common denominator and alter the fractions accordingly

Can you multiply fractions that have a different demonminator?

Yes. When multiplying and dividing fractions your denominators do not have to be the same. The denominators only haveto be the same if you are subtracting or adding them.
