Question

Which Number is a factor of 20 but not a multiple of two
12
5
10
4

Answer 1

The awnser is five I hope I helped you

Answer 2

The best way to do this is just to simply list at all of the possible factors of 20 and then take out those which are multiples of 2:

20 = 1, 2, 4, 5, 10, 20

Minus the multiples of 2:

Leaves only 1 and 5

The only option of these two on the list is 5 so the answer must be 5
