Question

Identify each classification of the real number system that can describe the set of numbers shown {3, 9, 147, 400}

) Integer
) Irrational
) Real
) Rational
) Whole
) Natural​

Answer 1

Explanation:

all of these 4 numbers are

integer (whole numbers positive and negative).

real (every whole number can be written as e.g. 3.0 and is part of the real numbers).

rational (as any whole number can be written as e.g. 3/1 and is part of the rational numbers).

whole (no fractions).

natural (they are in the set of [1, 2, 3, ... infinity) ).

the only thing here they are not is irrational, as to be irrational they would need to have an infinite sequence of digits after the decimal point without any repeating pattern.
