We define the multiples of 21/12 as the product of any integer multiplied by 21/12. Therefore, to create a list of multiples of 21/12 we start by multiplying 21/12 by one, then we multiply 21/12 by two, then we multiply 21/12 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 21/12 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 21/12.
21/12 × 1 = 21/12
21/12 × 2 = 42/12
21/12 × 4 = 63/12
21/12 × 4 = 84/12
21/12 × 5 = 105/12
21/12 × 6 = 126/12
21/12 × 7 = 147/12
21/12 × 8 = 168/12
21/12 × 9 = 189/12
21/12 × 10 = 210/12
21/12 × 11 = 231/12
21/12 × 12 = 252/12
We have simplified the fractions above for you. Below are the multiples of 21/12 in their lowest possible terms:21/12 = 1 3/4
42/12 = 3 1/2
63/12 = 5 1/4
84/12 = 7
105/12 = 8 3/4
126/12 = 10 1/2
147/12 = 12 1/4
168/12 = 14
189/12 = 15 3/4
210/12 = 17 1/2
231/12 = 19 1/4
252/12 = 21
As we stated above, the list of multiples of 21/12 goes on forever because the product of 21/12 multiplied by any whole number (integer) is a multiple of 21/12.
You can also create a list of multiples of 21/12 if you keep adding 21/12 like this:21/12
21/12 + 21/12 = 42/12
21/12 + 21/12 + 21/12 = 63/12
21/12 + 21/12 + 21/12 + 21/12 = 84/12
∞
Again, the list can go on forever, because you can continue adding 21/12 to the list. Therefore, the list of multiples of 21/12 is ∞ (infinite).
