(2)	0	✕	✔	✔	✔
(3)	−7
(4)	$\frac{-4}{3}$
(5)	$\frac{1}{2}$
(6)	$-\frac{1}{3}$
(7)	$\frac{-1}{-5}$

Answer 1

Natural number: Natural numbers are counting numbers: 1, 2, 3, 4, 5, …
Whole numbers: Whole numbers include all the natural numbers including 0.
Integers: The numbers that include the positive counting numbers, the negative counting numbers and 0 are called integers. Thus, the numbers such as …–3, –2, –1, 0, 1, 2, 3… are called integers.
Rational number: Any number which can be expressed in the form of $\frac{p}{q}$, where p and q are integers and q ≠ 0,is called a rational number.
