Best Answer

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.

Then add and simplify.

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

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.

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