3.5 and 3.75?
There is no whole number between 2 and 3. But decimals like 2.1, 2.2, 2.3 etc can be considered numbers between 2 and 3
Not "number", but "numbers" - there are infinitely many. For a start, get a decimal approximation (on your calculator) for the square root of 2 and 3, then get some terminating decimals that are between those.
For the first part: 2.5 - 2.4 = 0.1 2-digit decimals have an interval of 0.01. 0.1 / 0.01 = 10. Since the endpoints are presumably not included ("between"), you have to count one less (10 - 1 = 9). (If you include both endpoints, you would actually have one more: 10 + 1 = 11.) The reasoning is similar for part 2 and 3.
