By finding a common denominator for both fractions.
If you have 1/2 and 1/3, a common denominator would be 6, and you would re-write the equation to be 3/6 and 2/6. (remember, if you multiply the denominator by a number, you must multiply the numerator by the same number!)
Now that the equation is 3/6 and 2/6, the answer is seen as 5/6.
(But how did I know that a common denominator would be six? I just multiplied the original two denominators together. Not exactly elegant, but it works each time.)

How do you minnous fractions?
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

Do you have to have the same denominator when you subtract fractions?
Yes, but the numerator is different,same as adding fractions
Before adding or subtracting Why are fractions turned into like fractions?
They have to have the same denominator.
What is the rule in adding fractions having the same denominator?
Sum of the fractions = sum of numerators divided by their common denominator. Adding Fractions rule implies to addition of fractions having same denominator and as well as adding fractions with different denominators. So rule for adding fractions having the same denominator is add the numerators and simplify For example : 3/5 + 2/5 + 9/5 = (3 + 2 + 9)/5 [add the numerators] = 14/5
Does the denominator have to be the same when adding a fraction?
When adding two or more unlike fractions, yes.
