Because to add fractions, the denominators must be equal.

unlike 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.
What is the definition of Adding and Subtracting Like Fractions
Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.
Because to add fractions, the denominators must be equal.
The question is based on a complete misunderstanding of what is required. Unlike denominators are NOT required!
unlike fractions
unlike fractions
convert at least one of them so that they have the same denominator, then proceed with the addition or subtraction
It will enable you to add and subtract fractions with unlike denominators.
fractions having same denominators are like fractions & others are unlike 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.
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.
