10 and 20
The only multiples of 10 between 100 and 200 are 110, 120, 130, 140, 150, 160, 170, 180, 190. Among these, the even numbers are 110, 120, 130, 140, 150, 160, 170, and 180. The even multiples of 10 greater than 100 but less than 200 are 120, 140, 160, and 180. Thus, the even multiples of 10 in that range are 120, 140, 160, and 180.
-10 is 110 less than 100.
Leaving out non-positive multiples, the answer is 5, 10, 15 and 20.
Nothing. Any number that is less than 18/100 it must be less than 3/10.
