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