Quizplus · Accepted Answer

$-12.2$ is a rational number because it can be expressed as a fraction (e.g., $-122/10$) and it is also a real number. It is not an integer, natural number, or irrational number.

If R Is the Set of Real Numbers, Q Is −12.2- 12.2−12.2

If R Is the Set of Real Numbers, Q Is $- 12.2$
