Question

For homework Rio is listing some examples of real numbers in a diagram natural 6 whole -1 integer 0 rational .5 Which number did Rio Place incorrectly?

Answer 1

Whole numbers are similar to natural(non-negative, non-fractional). The only difference is that it includes the 0.

In this question, Rio placed -1 as an example of whole number. Since -1 is negative, it is not a whole number, so this the number which Rio placed incorrectly.
