Question

is every natural no a whole no. and vice versa ?justofy

Answer 1

yes every natural no. is a whole no. but not vice versa because
every whole no. is not a natural no.
ex.0 is a whole no. but not a natural no.

Answer 2

hey friend! here is your answer-
yes, every national number is whole number.
justification- because natural number define says that all numbers excluding 0.
                    and whole number define says all number including 0.
so, now all numbers are there in whole number including zero, thereby all natural numbers are whole numbers.
eg- in natural numbers it starts from 1 to infinity so,
      in whole number it starts from 0 but has 1 till infinity also.
so, we can say whole numbers are bigger family of numbers including 0.
hope it helps. please mark it brainliest.
