Find their least common denominator and convert them.
it stay the same when you subtract fractions and when you add fractions.
no, to add and subtract like and unlike fractions the denominator has to be the same,
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
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.
We can only add or subtract fractions if they have the same denominators
irregular fractions! ex. if the equation is 2 3/4, you would multiply 2*4, then add three. that is your numerator, denominator will stay the same. it will =11/4
numerators you add, denominators you leave it the same
Yes.
if it has a denominator
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.
first make denominators the same and add.
In order to add or subtract fractions, they must have the same denominator.
