Answer 1

Rational

Explanation:

Hello!

All rational numbers can be expressed as a fraction with integer parts.

-2 and 3 are integers and are represented as a fraction, so it is rational.

For decimals, any decimal that has repeating digits, or a pattern (ex 0.3333.... or 0.12312312...) are rational. Decimals without repeating digits or no pattern (ex pi: 3.1415....) are irrational.
