We define the multiples of 21/18 as the product of any integer multiplied by 21/18. Therefore, to create a list of multiples of 21/18 we start by multiplying 21/18 by one, then we multiply 21/18 by two, then we multiply 21/18 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 21/18 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 21/18.
21/18 × 1 = 21/18
21/18 × 2 = 42/18
21/18 × 4 = 63/18
21/18 × 4 = 84/18
21/18 × 5 = 105/18
21/18 × 6 = 126/18
21/18 × 7 = 147/18
21/18 × 8 = 168/18
21/18 × 9 = 189/18
21/18 × 10 = 210/18
21/18 × 11 = 231/18
21/18 × 12 = 252/18
We have simplified the fractions above for you. Below are the multiples of 21/18 in their lowest possible terms:21/18 = 1 1/6
42/18 = 2 1/3
63/18 = 3 1/2
84/18 = 4 2/3
105/18 = 5 5/6
126/18 = 7
147/18 = 8 1/6
168/18 = 9 1/3
189/18 = 10 1/2
210/18 = 11 2/3
231/18 = 12 5/6
252/18 = 14
As we stated above, the list of multiples of 21/18 goes on forever because the product of 21/18 multiplied by any whole number (integer) is a multiple of 21/18.
You can also create a list of multiples of 21/18 if you keep adding 21/18 like this:21/18
21/18 + 21/18 = 42/18
21/18 + 21/18 + 21/18 = 63/18
21/18 + 21/18 + 21/18 + 21/18 = 84/18
∞
Again, the list can go on forever, because you can continue adding 21/18 to the list. Therefore, the list of multiples of 21/18 is ∞ (infinite).
