How many numbers contain 9 from 1 to 999?
262. Here's how:Let's look at 1 to 99, where 18 number contain a 9 digit. First there is 1 to 89, which 8 numbers contain the nine: {9,19,29,...89}, then all ten of the 90's have a 9, so that's 18. The next 8 groups, [101-199], [201-299] ... [801-899] follow this same pattern. and finally all 100 of the numbers [900 - 999] contain a 9.So it is 100 + (9 x 18) = 262This assumes you mean whole numbers only, as decimals or rationals would create an infinite set of numbers (unless you limited it to a certain number of decimal places)
