We define the multiples of 15/21 as the product of any integer multiplied by 15/21. Therefore, to create a list of multiples of 15/21 we start by multiplying 15/21 by one, then we multiply 15/21 by two, then we multiply 15/21 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 15/21 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 15/21.
15/21 × 1 = 15/21
15/21 × 2 = 30/21
15/21 × 4 = 45/21
15/21 × 4 = 60/21
15/21 × 5 = 75/21
15/21 × 6 = 90/21
15/21 × 7 = 105/21
15/21 × 8 = 120/21
15/21 × 9 = 135/21
15/21 × 10 = 150/21
15/21 × 11 = 165/21
15/21 × 12 = 180/21
We have simplified the fractions above for you. Below are the multiples of 15/21 in their lowest possible terms:15/21 = 5/7
30/21 = 1 3/7
45/21 = 2 1/7
60/21 = 2 6/7
75/21 = 3 4/7
90/21 = 4 2/7
105/21 = 5
120/21 = 5 5/7
135/21 = 6 3/7
150/21 = 7 1/7
165/21 = 7 6/7
180/21 = 8 4/7
As we stated above, the list of multiples of 15/21 goes on forever because the product of 15/21 multiplied by any whole number (integer) is a multiple of 15/21.
You can also create a list of multiples of 15/21 if you keep adding 15/21 like this:15/21
15/21 + 15/21 = 30/21
15/21 + 15/21 + 15/21 = 45/21
15/21 + 15/21 + 15/21 + 15/21 = 60/21
∞
Again, the list can go on forever, because you can continue adding 15/21 to the list. Therefore, the list of multiples of 15/21 is ∞ (infinite).
