We define the multiples of 9/20 as the product of any integer multiplied by 9/20. Therefore, to create a list of multiples of 9/20 we start by multiplying 9/20 by one, then we multiply 9/20 by two, then we multiply 9/20 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 9/20 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 9/20.
9/20 × 1 = 9/20
9/20 × 2 = 18/20
9/20 × 4 = 27/20
9/20 × 4 = 36/20
9/20 × 5 = 45/20
9/20 × 6 = 54/20
9/20 × 7 = 63/20
9/20 × 8 = 72/20
9/20 × 9 = 81/20
9/20 × 10 = 90/20
9/20 × 11 = 99/20
9/20 × 12 = 108/20
We have simplified the fractions above for you. Below are the multiples of 9/20 in their lowest possible terms:9/20 = 9/20
18/20 = 9/10
27/20 = 1 7/20
36/20 = 1 4/5
45/20 = 2 1/4
54/20 = 2 7/10
63/20 = 3 3/20
72/20 = 3 3/5
81/20 = 4 1/20
90/20 = 4 1/2
99/20 = 4 19/20
108/20 = 5 2/5
As we stated above, the list of multiples of 9/20 goes on forever because the product of 9/20 multiplied by any whole number (integer) is a multiple of 9/20.
You can also create a list of multiples of 9/20 if you keep adding 9/20 like this:9/20
9/20 + 9/20 = 18/20
9/20 + 9/20 + 9/20 = 27/20
9/20 + 9/20 + 9/20 + 9/20 = 36/20
∞
Again, the list can go on forever, because you can continue adding 9/20 to the list. Therefore, the list of multiples of 9/20 is ∞ (infinite).
