Answer 1

The number 1.18 belongs to the set of rational numbers. Therefore, the correct option is:

rational numbers

1.18 can be expressed as a fraction (for example, 118/100), which is the defining characteristic of rational numbers. It is not a natural number, whole number, or integer since it is not a whole number. It is also not an irrational number, as irrationals cannot be expressed as a fraction.
