Because all that is needed is to add the numerators as for example 3/12 plus 4/12 equals 7/12

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
When doing fractions why is it easier to multiply and divide fractions than add and substract fractions?
It is easier to multiply or divide fractions than to add or subtract fractions because in multiplication, you just have to multiply the numerator by the numerator and the denominator by the denominator. Same applies with division of fractions, except that you have to reciprocate the fraction you're dividing with (divisor) then proceed to multiplication. Whereas, in addition and subtraction of fractions, you still have to get their Least Common Denominator (LCD).
How do you add fractions with same numerator?
if it has a denominator
Why is it easy to subtract and add with the fraction that has the same donominator?
When adding or subtracting fractions with the same denominator, it is easier because we can simply add or subtract the numerators and keep the denominator the same. The denominators are already equal, so no additional calculations or adjustments are necessary. This simplifies the math and makes it easier to compute the result.
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,

How do you add and subtract fractions with the same denominator?
it stay the same when you subtract fractions and when you add fractions.

When you add fractions are you supposed to have the same denominator?
Yes, you are.
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,
How do you add two fractions with the same denominator?
numerators you add, denominators you leave it the same
Why do you need a common denominator with fractions?
You can add or subtract fractions only if they are "like" fractions, that is, only if they have the same denominator - unless you know your fractions really well.
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 are fractions under addition?
In order to add or subtract fractions, they must have the same denominator.
