Only fractions with the same denominator can be added directly. Addition of such fractions can be achieved by adding their numerators to form the numerator of the sum, with the common denominator of the added fractions constituting the denominator of the sum. In this instance, 2/3 = 6/9, and 4/9 + 6/9 = 10/9.

To subtract fractions, find a common denominator. The common denominator of 6 and 8 is 24. Therefore, five sixths is equivalent to twenty-fours sixths, and five eighths is equivalent to twenty-four eighths. Subtracting twenty-four eighths from twenty-four sixths gives an answer of three twenty-fourths.

To compare two fractions, find a common denominator (multiplying the two denominators will always give you a common denominator), convert both fractions to the common denominator, then compare. Another - actually easier - way to compare two fractions is to convert both to decimal. Just pick up a calculator, and divide the numerator by the denominator.

8/18 12/27 16/36 just multiply the numerator and the denominator by the same value.

if you have a common denominator, the answer will remain the number that the common denominator is. like say the fraction is 3/4-2/4 (three over four minus two over four), the answer would be 1/4 (one over four)

First you find a common denominator, then you convert both fractions to the common denominator. For the common denominator, find a number that is divisible by both denominators. Just multiplying both will work, but this is not always the most efficient method, since this may cause you more work later, to simplify the result. Once you decide on a common denominator, in both fractions multiply the numerator and the denominator by the same number. Example: 1/3 + 1/4 Common denominator is 12 Multiply the first fraction by 4/4, and the second by 3/3, to obtain: 4/12 + 3/12

If you cant find a common denominator for two numbers you multiply them together which in this case would be 72 then you just symplify.
