We define the multiples of 21/3 as the product of any integer multiplied by 21/3. Therefore, to create a list of multiples of 21/3 we start by multiplying 21/3 by one, then we multiply 21/3 by two, then we multiply 21/3 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 21/3 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 21/3.
21/3 × 1 = 21/3
21/3 × 2 = 42/3
21/3 × 4 = 63/3
21/3 × 4 = 84/3
21/3 × 5 = 105/3
21/3 × 6 = 126/3
21/3 × 7 = 147/3
21/3 × 8 = 168/3
21/3 × 9 = 189/3
21/3 × 10 = 210/3
21/3 × 11 = 231/3
21/3 × 12 = 252/3
We have simplified the fractions above for you. Below are the multiples of 21/3 in their lowest possible terms:21/3 = 7
42/3 = 14
63/3 = 21
84/3 = 28
105/3 = 35
126/3 = 42
147/3 = 49
168/3 = 56
189/3 = 63
210/3 = 70
231/3 = 77
252/3 = 84
As we stated above, the list of multiples of 21/3 goes on forever because the product of 21/3 multiplied by any whole number (integer) is a multiple of 21/3.
You can also create a list of multiples of 21/3 if you keep adding 21/3 like this:21/3
21/3 + 21/3 = 42/3
21/3 + 21/3 + 21/3 = 63/3
21/3 + 21/3 + 21/3 + 21/3 = 84/3
∞
Again, the list can go on forever, because you can continue adding 21/3 to the list. Therefore, the list of multiples of 21/3 is ∞ (infinite).
