no, to add and subtract like and unlike fractions the denominator has to be the same,

In order to add or subtract fractions, they must have the same denominator.

The same as with positive ones. Make sure they have the same denominator and add or subtract their numerators.

he fact that they are improper is irrelevant. Re-scale the fractions so that they have the same denominator and thenadd or subtract as required.

You need a common denominator in order to add or subtract fractions.

If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.

You can add or subtract fractions only if they are "like" fractions, that is, only if they have the same denominator - unless you know your fractions really well.

You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.

The denominators must be the same before you can add or subtract fractions.

We can only add or subtract fractions if they have the same denominators

It stays the same. Only the numerators change.

Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.

Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.

If you are adding or subtracting fractions with the same denominator, you can add or subtract the numerators and keep the denominator the same. 1/8 + 3/8+ 3/8 = 7/8, for example

In order to add or subtract one fraction from another, they must have a common denominator, or the same denominator. That's because it's impossible to add two fractions that have a different number of parts.

Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.

Yes you have to add with the same denominator. when ever you do fractions they have to have the same denominator no matter what. So thats a yes

The denominator (bottom number) must be the same for all the fractions being added or subtracted together.

I am not entirely sure what you mean, but if you need to add, subtract, or compare two fractions, they need to have the same denominator.

They are called like fractions.In order to add or subtract fractions you will usually need to convert them to like fractions. Then you simply add or subtract the numerators (as required) to form the numerator of the answer. The same (or common) denominator is the denominator of the answer. You may need to simplify the resulting fraction.

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 :)

Find theLeast Common Denominator (LCD)Find the equivalent fractions.Add or subtract the fractions and add or subtract the whole numbers.Write your answer in lowest terms.

A common denominator is required to add or subtract fractions and not otherwise.

convert at least one of them so that they have the same denominator, then proceed with the addition or subtraction

To get the right answer when you add or subtract unlike fractions.
