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.

Ensure that the denominators are the same when adding or subtracting fractions.

In fractions, the denominator is the bottom number. When adding or subtracting fractions, it is helpful if all the denominators are the same. To do this, we look for common denominators, which is the same process as finding the least common multiple.

What is the definition of Adding and Subtracting Like Fractions

Common denominators.

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

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

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

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

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

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.

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

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

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).

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

When adding or subtracting fractions with different denominators and when reducing fractions to their lowest terms

Yes inasmuch that the denominators of the fractions must be common to each other.

it means to leave the denominators the same and add the numerators

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.
