We define the multiples of 21/39 as the product of any integer multiplied by 21/39. Therefore, to create a list of multiples of 21/39 we start by multiplying 21/39 by one, then we multiply 21/39 by two, then we multiply 21/39 by three, and so on.
To multiply a fraction by an integer, we leave the denominator alone and multiply the numerator by the integer. It is impossible to give you a list of all multiples of 21/39 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 21/39.
21/39 × 1 = 21/39
21/39 × 2 = 42/39
21/39 × 4 = 63/39
21/39 × 4 = 84/39
21/39 × 5 = 105/39
21/39 × 6 = 126/39
21/39 × 7 = 147/39
21/39 × 8 = 168/39
21/39 × 9 = 189/39
21/39 × 10 = 210/39
21/39 × 11 = 231/39
21/39 × 12 = 252/39
We have simplified the fractions above for you. Below are the multiples of 21/39 in their lowest possible terms:21/39 = 7/13
42/39 = 1 1/13
63/39 = 1 8/13
84/39 = 2 2/13
105/39 = 2 9/13
126/39 = 3 3/13
147/39 = 3 10/13
168/39 = 4 4/13
189/39 = 4 11/13
210/39 = 5 5/13
231/39 = 5 12/13
252/39 = 6 6/13
As we stated above, the list of multiples of 21/39 goes on forever because the product of 21/39 multiplied by any whole number (integer) is a multiple of 21/39.
You can also create a list of multiples of 21/39 if you keep adding 21/39 like this:21/39
21/39 + 21/39 = 42/39
21/39 + 21/39 + 21/39 = 63/39
21/39 + 21/39 + 21/39 + 21/39 = 84/39
∞
Again, the list can go on forever, because you can continue adding 21/39 to the list. Therefore, the list of multiples of 21/39 is ∞ (infinite).
