We define the multiples of 21/81 as the product of any integer multiplied by 21/81. Therefore, to create a list of multiples of 21/81 we start by multiplying 21/81 by one, then we multiply 21/81 by two, then we multiply 21/81 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 21/81 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 21/81.
21/81 × 1 = 21/81
21/81 × 2 = 42/81
21/81 × 4 = 63/81
21/81 × 4 = 84/81
21/81 × 5 = 105/81
21/81 × 6 = 126/81
21/81 × 7 = 147/81
21/81 × 8 = 168/81
21/81 × 9 = 189/81
21/81 × 10 = 210/81
21/81 × 11 = 231/81
21/81 × 12 = 252/81
We have simplified the fractions above for you. Below are the multiples of 21/81 in their lowest possible terms:21/81 = 7/27
42/81 = 14/27
63/81 = 7/9
84/81 = 1 1/27
105/81 = 1 8/27
126/81 = 1 5/9
147/81 = 1 22/27
168/81 = 2 2/27
189/81 = 2 1/3
210/81 = 2 16/27
231/81 = 2 23/27
252/81 = 3 1/9
As we stated above, the list of multiples of 21/81 goes on forever because the product of 21/81 multiplied by any whole number (integer) is a multiple of 21/81.
You can also create a list of multiples of 21/81 if you keep adding 21/81 like this:21/81
21/81 + 21/81 = 42/81
21/81 + 21/81 + 21/81 = 63/81
21/81 + 21/81 + 21/81 + 21/81 = 84/81
∞
Again, the list can go on forever, because you can continue adding 21/81 to the list. Therefore, the list of multiples of 21/81 is ∞ (infinite).
