They are the same as the even numbers in that range.
21 and 28 are the two multiples.
They are 10 and 20
Multiple is just a number that the number will go in to. Examples: Multiples of 3: 3, 6, 9, 12, 15, ... Multiples of 20: 20, 40, 60, 80, ... Not sure what your question is asking "between 200", but I hope my examples helped.
2, 4, 6, 8 or 0
For a number to have [only] 2 factors, it must be a prime number; the prime numbers between 0 and 20 are; 2, 3, 5, 7, 11, 13, 17, 19
21 and 28 are the two multiples.
0, 20, 40, etc. (just add 20 at a time, or multiply 0 x 20, 1 x 20, 2 x 20, etc.)
Even numbers have to end with 2, 4, 6, 8, or 0. And multiples of 5 have to end in 5 or 0.
2, 4, 6, 8, 10, 12, 14, 16, 18, 20
They are 10 and 20
10, 20, 30 and 40
They are: 10 20 30 and 40
The only multiples of 2 are 1 and 2 because it's a prime number, but if you meant first 2 multiples of 20 then it's also 1 and 2.

There are 10 multiples of 6 in that range.
Because 20 is a multiple of 4. All multiples of 20 are also multipples of 2, 5 and 10
