First, you must make sure that the denominators are the same, so if you are adding 3/6 + 4/8, you have to make the denominators the same, but how?
to make the denominators the same, you have to find the LCM, which is the least common multiple, and in this case, 24 is the LCM, and so your fraction will look like this; 3*4/6*4 + 4*3/8*3, so now you have to multiply, and the answer will be 12/24 + 12/24, but remember DON'T ADD THE DENOMINATORS!!, so your answer will be 24/24 which can also be written as 1.
You need to ensure the denominators are the same, and this involves finding the LCM (the lowest common multiples). Once you have done this you add or subtract the numerators
eg
4/7 + 2/3
The LCM of 7 and 3 is 21, so you need to change the equation to read
12/21 + 14/21 = (12+14)/21 = 26/21 = 1 and 5/21.
In subtraction you take away rather than add. Also, addition is commutative, subtraction is not so the order of the numbers does matter for subtraction.
It assists in the proper addition and subtraction of fractions.
Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.
To model addition and subtraction of mixed fractions, first convert each mixed fraction into an improper fraction. Then, find a common denominator to align the fractions. Once they have a common denominator, perform the addition or subtraction of the numerators while keeping the denominator the same. Finally, if needed, convert the resulting improper fraction back into a mixed fraction for the final answer.
yeah~!! fractions are 2 between the symbol of subtraction or addition to multiply the single denominator not the married denominator or either the in a relationship numerator... ehehhehehe hope it helped ~ BOLD

like fractions
Addition or subtraction of fractions require "like" fractions: that is, fractions with the same denominator.
You don't. You use the GCF to reduce the answer once the addition or subtraction is complete.
