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