How many natural numbers?<br> from 78 to 234<br> how many whole numbers <br> from 24 to 721
Vinil7 [7]

Answer:

<u>158 natural numbers from 78 to 234, and 699 whole numbers from 24 to 721.</u>

Step-by-step explanation:

Natural numbers are positive integers (whole numbers), so all numbers from the range of 78 to 234 would be included, including 78 and 234 itself. That is 158 natural numbers. Whole numbers are numbers without a fraction or decimal, they are integers. So all numbers from 24 to 721 would be included, as well as 24 and 721 itself. That is 699 whole numbers from 24 to 721. Hope this helps.
