We define the multiples of 21/60 as the product of any integer multiplied by 21/60. Therefore, to create a list of multiples of 21/60 we start by multiplying 21/60 by one, then we multiply 21/60 by two, then we multiply 21/60 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 21/60 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 21/60.
21/60 × 1 = 21/60
21/60 × 2 = 42/60
21/60 × 4 = 63/60
21/60 × 4 = 84/60
21/60 × 5 = 105/60
21/60 × 6 = 126/60
21/60 × 7 = 147/60
21/60 × 8 = 168/60
21/60 × 9 = 189/60
21/60 × 10 = 210/60
21/60 × 11 = 231/60
21/60 × 12 = 252/60
We have simplified the fractions above for you. Below are the multiples of 21/60 in their lowest possible terms:21/60 = 7/20
42/60 = 7/10
63/60 = 1 1/20
84/60 = 1 2/5
105/60 = 1 3/4
126/60 = 2 1/10
147/60 = 2 9/20
168/60 = 2 4/5
189/60 = 3 3/20
210/60 = 3 1/2
231/60 = 3 17/20
252/60 = 4 1/5
As we stated above, the list of multiples of 21/60 goes on forever because the product of 21/60 multiplied by any whole number (integer) is a multiple of 21/60.
You can also create a list of multiples of 21/60 if you keep adding 21/60 like this:21/60
21/60 + 21/60 = 42/60
21/60 + 21/60 + 21/60 = 63/60
21/60 + 21/60 + 21/60 + 21/60 = 84/60
∞
Again, the list can go on forever, because you can continue adding 21/60 to the list. Therefore, the list of multiples of 21/60 is ∞ (infinite).
