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.

It will enable you to add and 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

fractions having same denominators are like fractions & others are unlike fractions

Unlike. Unlike. Unlike. Unlike.

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.

Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.
