The fraction that have the greatest numerator.
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
The fraction with the greater denominator is less. For example, 1/2 is greater than 1/3 while 1/3 has the greater denominator.
Possible reasons: To add or subtract fractions, To compare fractions with different denominators.
You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent fractions.
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.
Only if the denominators are different.
it stay the same when you subtract fractions and when you add 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 subract other fractions to it, or reduce it.
sex is very nice :3
with different denominators, just get their lcd and that will serve as they're denominator.
Fractions! Otherwise you don't have anything to add.
In fractions, you can NEVER add or subtract
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).
Dissimilar fractions have different denominators and their lowest common denominator must be found in order to add them up.
because you can find out different amounts put together
YOU JUST CANT....go on you try it
You convert to a common denominator first. Then you add or subtract the numerator and write it in simplest form
Change them into mixed numbers and add the integers and fractions together ensuring that the fractions have a common denominator.
You need a common denominator in order to add or subtract fractions.
When you want to add fractions that have different denominators, you have to convert them into fractions that do have the same denominators. So for example, how much is a half plus a third? Both of these can be converted into sixths, so one half equals three sixths, and one third equals two sixths. Three sixths plus two sixths equals five sixths. That's the answer. If you have three fractions with different denominators, the procedure is the same. Convert all three into fractions with the same denominators, then add them.
