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.
9/2 + 9/2
Nothing actually happens. You are now in a position where the fractions may be added or subtracted more easily but that is all.
Because God made it so O.o
LCD is the Lowest Common Denominator which is the lowest number into which the denominators of all the fractions will each divide exactly. Each of the fractions can then be converted to an equivalent fraction with the new denominator which then allows the fractions to be added and/or subtracted.
There is no such thing as THE two fractions. There are infinitely many fractions.
5/8 and 5/8
When the denominators of two or more fractions are the SAME, then they can be added or subtracted directly. An easy way is to multiply each denominator by the other (along with its corresponding numerator).
1/2 + 1 1/2=2
1 fifth and 2 fifths
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.
