no, to add and subtract like and unlike fractions the denominator has to be the same,
Because that is not how addition of fractions is defined.
When you want to add or subtract unlike fractions.
Like fractions have the same denominator, unlike fractions don't.
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.

Finding the LCM will make adding and subtracting fractions easier.
Because to add fractions, the denominators must be equal.
You first convert them to equivalent fractions with a common denominator. Or you convert them to decimal 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. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

because its just one of the rules of math :)

To add and subtract unlike fractions.
When you want to add or subtract unlike fractions.
You look for a common denominator; convert the fractions to equivalent fractions with the denominator you found; then you do the addition itself.
To get the right answer when you add or subtract unlike fractions.
