For a set to be closed under any operation, the result of the operation must also be a member of the set. The result of adding fractions is another fraction, thus it is closed under addition. Remember that 8/3, 8/4, 4/4, 2/1 are all fractions - they have a numerator and denominator separated by a line (at an oblique angle on the computer screen). Improper fractions are still fractions.
The usual rules of addition of fractions apply.
Addition or subtraction of fractions require "like" fractions: that is, fractions with the same denominator.
You look for a common denominator; convert the fractions to equivalent fractions with the denominator you found; then you do the addition itself.
For addition, subtraction, division and multiplication with other fractions
The answer to an addition is called the sum. Fractions and other numbers.
Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.
Because that is not how addition of fractions is defined.
Yes, it applies to even multiplication of fractions and rational and irrational numbers.
It's impossible to list all fractions, because there are no least or greatest fractions. In addition, between any two fractions, there's another fraction (for example, the average of the two functions).
you should use addition in a problem involving fractions if you see key words that mean to add, for example sum increase, altogether, etc
Unlike fractions have denominators that are unequal, and therefore cannot be added or subtracted. If two fractions need to be added or subtracted they must first be converted to like fractions.
It assists in the proper addition and subtraction of fractions.
find a common denominator. Then just add across.
Same as for addition. Mainly, you have to convert the fractions to equivalent fractions that have the same denominator. After that, it is easy: just subtract the numerators and put the result on top of the common denominator.
Answer: When adding or subtracting fractions with different denominators it is important to change the denominators into the lowest common denominator by using equivalent fractions. Answer: Equivalent fractions are used to: * Simplify fractions. It is sort of inelegant to write the final solution of a problem as 123/246, when you can just as well write it as 1/2. * Add fractions. If two fractions have different denominators, you need to convert them to equivalent fractions that have the same denominator. Only then can you add. * Subtract fractions (same as addition). * Compare fractions, to check which one is larger (same as addition).
You don't. You use the GCF to reduce the answer once the addition or subtraction is complete.

The answer to any addition problem is called the Sum.
No Q is not cyclic under addition.
