i don't get it, i have got homework to create a venn diagram of natural and whole numbers aren't they both the same thing? how do i make a venn diagram for that?? it also says that what numbers belong outside the circle?
2. describe more accurate method of drawing the circles in venn diagram to address the problem you encountered in previous step.

Question: can a rational number be an irrational number at the same time? why or why not?

Natural numbers typically do not include "0" whereas whole numbers do include "0". The Venn Diagram would show natural and whole numbers overlap with all numbers that are greater than "0".

I'm not sure I understand, but maybe where x = 0 versus where x > 0. This may be more accurate than typing out every whole number (e.g. 1,2,3,4,5,6,7...to infinity) per the previous question.

Fractions and decimals are neither whole numbers nor natural numbers. So 1/2, 1/4, 1/9, 0.8, 0.1, etc. would be outside of the circle.
