We define the multiples of 21/10 as the product of any integer multiplied by 21/10. Therefore, to create a list of multiples of 21/10 we start by multiplying 21/10 by one, then we multiply 21/10 by two, then we multiply 21/10 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 21/10 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 21/10.
21/10 × 1 = 21/10
21/10 × 2 = 42/10
21/10 × 4 = 63/10
21/10 × 4 = 84/10
21/10 × 5 = 105/10
21/10 × 6 = 126/10
21/10 × 7 = 147/10
21/10 × 8 = 168/10
21/10 × 9 = 189/10
21/10 × 10 = 210/10
21/10 × 11 = 231/10
21/10 × 12 = 252/10
We have simplified the fractions above for you. Below are the multiples of 21/10 in their lowest possible terms:21/10 = 2 1/10
42/10 = 4 1/5
63/10 = 6 3/10
84/10 = 8 2/5
105/10 = 10 1/2
126/10 = 12 3/5
147/10 = 14 7/10
168/10 = 16 4/5
189/10 = 18 9/10
210/10 = 21
231/10 = 23 1/10
252/10 = 25 1/5
As we stated above, the list of multiples of 21/10 goes on forever because the product of 21/10 multiplied by any whole number (integer) is a multiple of 21/10.
You can also create a list of multiples of 21/10 if you keep adding 21/10 like this:21/10
21/10 + 21/10 = 42/10
21/10 + 21/10 + 21/10 = 63/10
21/10 + 21/10 + 21/10 + 21/10 = 84/10
∞
Again, the list can go on forever, because you can continue adding 21/10 to the list. Therefore, the list of multiples of 21/10 is ∞ (infinite).
