We define the multiples of 42/20 as the product of any integer multiplied by 42/20. Therefore, to create a list of multiples of 42/20 we start by multiplying 42/20 by one, then we multiply 42/20 by two, then we multiply 42/20 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 42/20 because the list goes on forever. However, here is the math to calculate the beginning list of multiples of 42/20.
42/20 × 1 = 42/20
42/20 × 2 = 84/20
42/20 × 4 = 126/20
42/20 × 4 = 168/20
42/20 × 5 = 210/20
42/20 × 6 = 252/20
42/20 × 7 = 294/20
42/20 × 8 = 336/20
42/20 × 9 = 378/20
42/20 × 10 = 420/20
42/20 × 11 = 462/20
42/20 × 12 = 504/20
We have simplified the fractions above for you. Below are the multiples of 42/20 in their lowest possible terms:42/20 = 2 1/10
84/20 = 4 1/5
126/20 = 6 3/10
168/20 = 8 2/5
210/20 = 10 1/2
252/20 = 12 3/5
294/20 = 14 7/10
336/20 = 16 4/5
378/20 = 18 9/10
420/20 = 21
462/20 = 23 1/10
504/20 = 25 1/5
As we stated above, the list of multiples of 42/20 goes on forever because the product of 42/20 multiplied by any whole number (integer) is a multiple of 42/20.
You can also create a list of multiples of 42/20 if you keep adding 42/20 like this:42/20
42/20 + 42/20 = 84/20
42/20 + 42/20 + 42/20 = 126/20
42/20 + 42/20 + 42/20 + 42/20 = 168/20
∞
Again, the list can go on forever, because you can continue adding 42/20 to the list. Therefore, the list of multiples of 42/20 is ∞ (infinite).
