How many numbers below 1000 are divisible by6?

Answer 1

166, or 167 if you count zero in your set of numbers below 1000 (or an infinite number, if you allow negative numbers and count them all as being below 1000).undefined

Every sixth number is divisible by six, so we can get a rough idea of the right answer by dividing 1000 by 6. That will give you 166.66666... or 166 2/3. Or, since we're talking about numbers below 1000, not actually including 1000, we could divide 999 by 6, getting 166.5, In either case we have 166 and a bit, and we have to decide what to do with the bit. In fact we need to lose the bit. To see this, look at a simpler example such as 10/6. That's 1.666... but there is only one number below 10 that's divisible by 6 (or two if you count zero). So you need to lose the .6666..., and then add 1 if you're counting zero as a natural number.
