If you have 20 tens you have 200. You don't need the rest.
From 1-100, it appears 20 times, in 19 different numbers.5152535455051525354555657585965758595For every interval of one hundred after that (101-200, 201-300, etc.) except for 500, it will be the same amount of fives. So, 20 instances times 9 different intervals (still excluding 500-599), there are 180 fives.Now we'll consider 500-599. From 0-99, there are 100 numbers, so there are also 100 numbers from 500-599. That means there is an extra 100 fives, for each 5 in the hundreds place. Add that to the original 20 from the tens and ones place, and there are 120 fives between 500-599.When we add that 120 on the our other 180, we arrive at the grand total of 300 fives between 1-1000.
Ten of them.
