Numbers between numbers

Are there numbers between numbers?

This one simple question can lead to hours of investigation!



What numbers are there between 0 and 1? What number would be half way in between? Where would a quarter go? What about three quarters? What about 0.5? 0.1? What would the number be half way between 0 and 0.1?

You can get real debate going here about how fractions work, how decimals work and how they relate to each other.

Have fun!
