Question

(Every natural number is a rational number but the vice-versa is not always true.
(i) Every whole number and integer is a rational number but vice-versa is not always true.

Answer 1

Answer:

• Every natural number is a rational number but the vice versa is not always true as rational numbers are in the form p/q. 2 is a natural number and in rational form it can be written as 2/1 which is also the same. But, 1/2 is a rational number which is not a natural number.
• Every whole number is a rational number but the vice versa is not always true. 0 is a whole number, integer and also a rational number. But 4/5 is neither whole or integer but only rational.
