We define the multiples of 21/8 as the product of any integer multiplied by 21/8. Therefore, to create a list of multiples of 21/8 we start by multiplying 21/8 by one, then we multiply 21/8 by two, then we multiply 21/8 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 21/8 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 21/8.
21/8 × 1 = 21/8
21/8 × 2 = 42/8
21/8 × 4 = 63/8
21/8 × 4 = 84/8
21/8 × 5 = 105/8
21/8 × 6 = 126/8
21/8 × 7 = 147/8
21/8 × 8 = 168/8
21/8 × 9 = 189/8
21/8 × 10 = 210/8
21/8 × 11 = 231/8
21/8 × 12 = 252/8
We have simplified the fractions above for you. Below are the multiples of 21/8 in their lowest possible terms:21/8 = 2 5/8
42/8 = 5 1/4
63/8 = 7 7/8
84/8 = 10 1/2
105/8 = 13 1/8
126/8 = 15 3/4
147/8 = 18 3/8
168/8 = 21
189/8 = 23 5/8
210/8 = 26 1/4
231/8 = 28 7/8
252/8 = 31 1/2
As we stated above, the list of multiples of 21/8 goes on forever because the product of 21/8 multiplied by any whole number (integer) is a multiple of 21/8.
You can also create a list of multiples of 21/8 if you keep adding 21/8 like this:21/8
21/8 + 21/8 = 42/8
21/8 + 21/8 + 21/8 = 63/8
21/8 + 21/8 + 21/8 + 21/8 = 84/8
∞
Again, the list can go on forever, because you can continue adding 21/8 to the list. Therefore, the list of multiples of 21/8 is ∞ (infinite).
