. Which of the following statements are true (T) and which are false (F)?

(e) All natural numbers are whole numbers.

True, that is because natural numbers start from 1 and whole numbers start from 0, which means all the natural numbers are included in the whole numbers, the only number that is missing is 0 so it is true because all natural numbers are included in the whole numbers, the only missing number is 0 as it is only in whole numbers.

the answer is true  because all natural numbers  are whole numbers . All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number.
