Subtract their numerators providing that they both have the same denominators.
When you subtract a fraction from itself. Two equivalent fractions also have a difference of zero.
Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
The difference is that they equivalent fractions worksheets have graphics and explain the concepts in easier to understand language. I find them to be an easier and fun way to introduce and explain fractions.
The LCM is used for integers, not fractions. If you're trying to add unlike fractions, take the LCM of the denominators (known in this case as the least common denominator, or LCD), convert the fractions and proceed.
find the lowest common denominator
There is no difference in value between "equal" fractions: the difference is zero.
If two fractions are equal then the difference between them is zero (0).
No, the relevant difference is 0.
Yes.

Find the lowest common multiple of the denominators and adjust the fractions accordingly
To find the sum of two mixed numbers, turn the mixed numbers into improper fractions (multiply the base with the denominator and add the numerator), then add the two fractions. To add the two fractions, find the LCD (lowest common denominator) and add the two numerators, but leave the denominators the same.

multiply the two denominators
Well, darling, after 2/3 comes 3/3, which is the same as 1 whole. So, if you're counting in fractions, it goes 1/3, 2/3, 3/3, and then you're back to square one with a full pie. Hope that clears things up for you!
Add them together, then divide by 2.
