How many fives are between 1 and 100?

Answer 1

5, 15, 25, 35, 45, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 65, 75, 85, 95. By counting them, there are twenty 5s between 1 and 100.

Actually...if by "between" the questioner intended to exclude the number 100, then there are only 19 5s "between" 1 and 100.

Answer 2

There are 20 fives between 1 and 100. This can be calculated by dividing 100 by 5, which equals 20. The numbers 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, and 100 are all multiples of 5 within that range.
