### Is -4 a natural number an integer or both?

It is only an integer, as natural numbers are all integers from
0 (e.g. 0, 1, 2, 3, 4…). According to another definition of the set
of natural numbers, integers from 1 are considered natural.
In other words, according to the first definition, the set of
natural numbers is all non-negative integers. According to the
second definition, the set of natural numbers is all positive
integers.

### Is the number 0 a natural number?

It depends on what you consider a natural number. If you
consider it to be the set of all integers starting from 1 and going
upward, then no, 0 is not a natural number.
However, if you consider a natural number to be the set of all
non-negative integers, then 0 is included in the set of natural
numbers.

### Are All rationals numbers are in the set of natural numbers?

1. No.
The Natural numbers are the positive integers (sometimes
the non-negative integers).
Rational numbers are numbers that can be expressed as the
quotient of two integers (positive or negative). All Natural
numbers are in the set of Rational numbers. 2. No. Natural
numbers are usually defined as integers greater than zero. A
Rational number is then defined simply as a number that can be
expressed as an integer divided by a natural number. (This
definition includes all rational numbers, but
excludes division by zero.)
