Question

is 8 - -2𝜋 a rational or an irrational number

Answer 1

An irrational number is a number that cannot be converted to a fraction. A rational number can be converted.

8 is a rational number because it can be a fraction (such as 72/9 or 64/8)

Pi is an irrational number because it has never ending decimals and cannot be converted to a fraction.

8-2*pi would be irrational because it is a number that has never ending decimals that cannot be converted to a fraction.
