We define the multiples of 21/7 as the product of any integer multiplied by 21/7. Therefore, to create a list of multiples of 21/7 we start by multiplying 21/7 by one, then we multiply 21/7 by two, then we multiply 21/7 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 21/7 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 21/7.
21/7 × 1 = 21/7
21/7 × 2 = 42/7
21/7 × 4 = 63/7
21/7 × 4 = 84/7
21/7 × 5 = 105/7
21/7 × 6 = 126/7
21/7 × 7 = 147/7
21/7 × 8 = 168/7
21/7 × 9 = 189/7
21/7 × 10 = 210/7
21/7 × 11 = 231/7
21/7 × 12 = 252/7
We have simplified the fractions above for you. Below are the multiples of 21/7 in their lowest possible terms:21/7 = 3
42/7 = 6
63/7 = 9
84/7 = 12
105/7 = 15
126/7 = 18
147/7 = 21
168/7 = 24
189/7 = 27
210/7 = 30
231/7 = 33
252/7 = 36
As we stated above, the list of multiples of 21/7 goes on forever because the product of 21/7 multiplied by any whole number (integer) is a multiple of 21/7.
You can also create a list of multiples of 21/7 if you keep adding 21/7 like this:21/7
21/7 + 21/7 = 42/7
21/7 + 21/7 + 21/7 = 63/7
21/7 + 21/7 + 21/7 + 21/7 = 84/7
∞
Again, the list can go on forever, because you can continue adding 21/7 to the list. Therefore, the list of multiples of 21/7 is ∞ (infinite).
