ANSWER

Rational number and Real number

Step-by-step explanation

We want to identify what type of number -3.7 is.

A natural number is a number that is a positive integer, used in counting things. Examples are 4, 7 and 55.

A whole number is a number that is used in counting, including 0 i.e. natural numbers including 0.

An integer is a whole number but the difference is that an integer can be positive, negative or zero.

A rational number is a number that can be expressed as a fraction of two integers i.e. a/b while an irrational number is one that cannot be expressed as a fraction of two integers.

A real number is any number that can be found as a distance between two points on the number line.

From the definitions above, we see that we can classify -3.7 as a rational number and a real number.

It is not a natural number, whole number, irrational number or an integer.
