How do you add and subtract fractions with the same denominator?
it stay the same when you subtract fractions and when you add fractions.
Do you add and subtract like and unlike fractions in the same way?
no, to add and subtract like and unlike fractions the denominator has to be the same,
When you add fractions do they have to 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
How is adding like fractions and adding unlike fractions the same?
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.
How do you add fractions without mixed numbers?
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
Fractions can be added and subtracted only if they're fractions?
We can only add or subtract fractions if they have the same denominators
How do you add three fractions without the same denominators?
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.
How do you add two fractions with the same denominator?
numerators you add, denominators you leave it the same
When you add fractions do you have to have the same denominator?
Yes.
How do you add fractions with same numerator?
if it has a denominator
How do you add fractions togather?
first make denominators the same and add.
Why are two fractions converted into like fractions?
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.
