Answer:

first one is rational, second is also rational, third is rational, fourth is rational, and fifth is irrational.

Step-by-step explanation:

Rational numbers are numbers that can be expressed as a fraction or part of a whole number. (examples: -7, 2/3, 3.75) Irrational numbers are numbers that cannot be expressed as a fraction or ratio of two integers. The reason why [tex]\sqrt{12}[/tex] is an irrational number is bc it's not a perfect square while[tex]\sqrt{49}[/tex] equals to 7 and is a perfect square.
