We define the multiples of 84/21 as the product of any integer multiplied by 84/21. Therefore, to create a list of multiples of 84/21 we start by multiplying 84/21 by one, then we multiply 84/21 by two, then we multiply 84/21 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 84/21 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 84/21.
84/21 × 1 = 84/21
84/21 × 2 = 168/21
84/21 × 4 = 252/21
84/21 × 4 = 336/21
84/21 × 5 = 420/21
84/21 × 6 = 504/21
84/21 × 7 = 588/21
84/21 × 8 = 672/21
84/21 × 9 = 756/21
84/21 × 10 = 840/21
84/21 × 11 = 924/21
84/21 × 12 = 1008/21
We have simplified the fractions above for you. Below are the multiples of 84/21 in their lowest possible terms:84/21 = 4
168/21 = 8
252/21 = 12
336/21 = 16
420/21 = 20
504/21 = 24
588/21 = 28
672/21 = 32
756/21 = 36
840/21 = 40
924/21 = 44
1008/21 = 48
As we stated above, the list of multiples of 84/21 goes on forever because the product of 84/21 multiplied by any whole number (integer) is a multiple of 84/21.
You can also create a list of multiples of 84/21 if you keep adding 84/21 like this:84/21
84/21 + 84/21 = 168/21
84/21 + 84/21 + 84/21 = 252/21
84/21 + 84/21 + 84/21 + 84/21 = 336/21
∞
Again, the list can go on forever, because you can continue adding 84/21 to the list. Therefore, the list of multiples of 84/21 is ∞ (infinite).
