**Luv4ever**, Saturday, January 9, 2010 at 5:01pmDo you know what divisible even means. Divisible means dividable. Try to divide all those numbers by 9.

a)81 = 81/9 = 9

b)162 = 162/9 = 18

c)199 = 199/0 = 22.11111..

d)1125 = 1125/9 = 125

From this you can see that the only number which is not divisible by 9 is 199.
