We define the multiples of 21/2 as the product of any integer multiplied by 21/2. Therefore, to create a list of multiples of 21/2 we start by multiplying 21/2 by one, then we multiply 21/2 by two, then we multiply 21/2 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 21/2 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 21/2.
21/2 × 1 = 21/2
21/2 × 2 = 42/2
21/2 × 4 = 63/2
21/2 × 4 = 84/2
21/2 × 5 = 105/2
21/2 × 6 = 126/2
21/2 × 7 = 147/2
21/2 × 8 = 168/2
21/2 × 9 = 189/2
21/2 × 10 = 210/2
21/2 × 11 = 231/2
21/2 × 12 = 252/2
We have simplified the fractions above for you. Below are the multiples of 21/2 in their lowest possible terms:21/2 = 10 1/2
42/2 = 21
63/2 = 31 1/2
84/2 = 42
105/2 = 52 1/2
126/2 = 63
147/2 = 73 1/2
168/2 = 84
189/2 = 94 1/2
210/2 = 105
231/2 = 115 1/2
252/2 = 126
As we stated above, the list of multiples of 21/2 goes on forever because the product of 21/2 multiplied by any whole number (integer) is a multiple of 21/2.
You can also create a list of multiples of 21/2 if you keep adding 21/2 like this:21/2
21/2 + 21/2 = 42/2
21/2 + 21/2 + 21/2 = 63/2
21/2 + 21/2 + 21/2 + 21/2 = 84/2
∞
Again, the list can go on forever, because you can continue adding 21/2 to the list. Therefore, the list of multiples of 21/2 is ∞ (infinite).
