We define the multiples of 21/4 as the product of any integer multiplied by 21/4. Therefore, to create a list of multiples of 21/4 we start by multiplying 21/4 by one, then we multiply 21/4 by two, then we multiply 21/4 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 21/4 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 21/4.
21/4 × 1 = 21/4
21/4 × 2 = 42/4
21/4 × 4 = 63/4
21/4 × 4 = 84/4
21/4 × 5 = 105/4
21/4 × 6 = 126/4
21/4 × 7 = 147/4
21/4 × 8 = 168/4
21/4 × 9 = 189/4
21/4 × 10 = 210/4
21/4 × 11 = 231/4
21/4 × 12 = 252/4
We have simplified the fractions above for you. Below are the multiples of 21/4 in their lowest possible terms:21/4 = 5 1/4
42/4 = 10 1/2
63/4 = 15 3/4
84/4 = 21
105/4 = 26 1/4
126/4 = 31 1/2
147/4 = 36 3/4
168/4 = 42
189/4 = 47 1/4
210/4 = 52 1/2
231/4 = 57 3/4
252/4 = 63
As we stated above, the list of multiples of 21/4 goes on forever because the product of 21/4 multiplied by any whole number (integer) is a multiple of 21/4.
You can also create a list of multiples of 21/4 if you keep adding 21/4 like this:21/4
21/4 + 21/4 = 42/4
21/4 + 21/4 + 21/4 = 63/4
21/4 + 21/4 + 21/4 + 21/4 = 84/4
∞
Again, the list can go on forever, because you can continue adding 21/4 to the list. Therefore, the list of multiples of 21/4 is ∞ (infinite).
