We define the multiples of 81/4 as the product of any integer multiplied by 81/4. Therefore, to create a list of multiples of 81/4 we start by multiplying 81/4 by one, then we multiply 81/4 by two, then we multiply 81/4 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 81/4 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 81/4.
81/4 × 1 = 81/4
81/4 × 2 = 162/4
81/4 × 4 = 243/4
81/4 × 4 = 324/4
81/4 × 5 = 405/4
81/4 × 6 = 486/4
81/4 × 7 = 567/4
81/4 × 8 = 648/4
81/4 × 9 = 729/4
81/4 × 10 = 810/4
81/4 × 11 = 891/4
81/4 × 12 = 972/4
We have simplified the fractions above for you. Below are the multiples of 81/4 in their lowest possible terms:81/4 = 20 1/4
162/4 = 40 1/2
243/4 = 60 3/4
324/4 = 81
405/4 = 101 1/4
486/4 = 121 1/2
567/4 = 141 3/4
648/4 = 162
729/4 = 182 1/4
810/4 = 202 1/2
891/4 = 222 3/4
972/4 = 243
As we stated above, the list of multiples of 81/4 goes on forever because the product of 81/4 multiplied by any whole number (integer) is a multiple of 81/4.
You can also create a list of multiples of 81/4 if you keep adding 81/4 like this:81/4
81/4 + 81/4 = 162/4
81/4 + 81/4 + 81/4 = 243/4
81/4 + 81/4 + 81/4 + 81/4 = 324/4
∞
Again, the list can go on forever, because you can continue adding 81/4 to the list. Therefore, the list of multiples of 81/4 is ∞ (infinite).
