We define the multiples of 80/90 as the product of any integer multiplied by 80/90. Therefore, to create a list of multiples of 80/90 we start by multiplying 80/90 by one, then we multiply 80/90 by two, then we multiply 80/90 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 80/90 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 80/90.
80/90 × 1 = 80/90
80/90 × 2 = 160/90
80/90 × 4 = 240/90
80/90 × 4 = 320/90
80/90 × 5 = 400/90
80/90 × 6 = 480/90
80/90 × 7 = 560/90
80/90 × 8 = 640/90
80/90 × 9 = 720/90
80/90 × 10 = 800/90
80/90 × 11 = 880/90
80/90 × 12 = 960/90
We have simplified the fractions above for you. Below are the multiples of 80/90 in their lowest possible terms:80/90 = 8/9
160/90 = 1 7/9
240/90 = 2 2/3
320/90 = 3 5/9
400/90 = 4 4/9
480/90 = 5 1/3
560/90 = 6 2/9
640/90 = 7 1/9
720/90 = 8
800/90 = 8 8/9
880/90 = 9 7/9
960/90 = 10 2/3
As we stated above, the list of multiples of 80/90 goes on forever because the product of 80/90 multiplied by any whole number (integer) is a multiple of 80/90.
You can also create a list of multiples of 80/90 if you keep adding 80/90 like this:80/90
80/90 + 80/90 = 160/90
80/90 + 80/90 + 80/90 = 240/90
80/90 + 80/90 + 80/90 + 80/90 = 320/90
∞
Again, the list can go on forever, because you can continue adding 80/90 to the list. Therefore, the list of multiples of 80/90 is ∞ (infinite).
