We define the multiples of 90/21 as the product of any integer multiplied by 90/21. Therefore, to create a list of multiples of 90/21 we start by multiplying 90/21 by one, then we multiply 90/21 by two, then we multiply 90/21 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 90/21 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 90/21.
90/21 × 1 = 90/21
90/21 × 2 = 180/21
90/21 × 4 = 270/21
90/21 × 4 = 360/21
90/21 × 5 = 450/21
90/21 × 6 = 540/21
90/21 × 7 = 630/21
90/21 × 8 = 720/21
90/21 × 9 = 810/21
90/21 × 10 = 900/21
90/21 × 11 = 990/21
90/21 × 12 = 1080/21
We have simplified the fractions above for you. Below are the multiples of 90/21 in their lowest possible terms:90/21 = 4 2/7
180/21 = 8 4/7
270/21 = 12 6/7
360/21 = 17 1/7
450/21 = 21 3/7
540/21 = 25 5/7
630/21 = 30
720/21 = 34 2/7
810/21 = 38 4/7
900/21 = 42 6/7
990/21 = 47 1/7
1080/21 = 51 3/7
As we stated above, the list of multiples of 90/21 goes on forever because the product of 90/21 multiplied by any whole number (integer) is a multiple of 90/21.
You can also create a list of multiples of 90/21 if you keep adding 90/21 like this:90/21
90/21 + 90/21 = 180/21
90/21 + 90/21 + 90/21 = 270/21
90/21 + 90/21 + 90/21 + 90/21 = 360/21
∞
Again, the list can go on forever, because you can continue adding 90/21 to the list. Therefore, the list of multiples of 90/21 is ∞ (infinite).
