-- Find a common denominator.
(It will be a number of which all three denominators are factors.
The best choice is their least common multiple.)
-- Change the fractions to their equivalents with the common denominator.
-- Then add their numerators to get the numerator of their sum.

When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?
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.
Do you add denominators in fractions?
No.
How do you add or subtract fractions with unlike denominators?
convert at least one of them so that they have the same denominator, then proceed with the addition or subtraction
How do you add and subtract by 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.
How do you add two fractions that have like denominators?
In fractions, you can NEVER add or subtract
