Question

An irrational number between -2 and -1

a rational number between -2 and -1

Answer 1

An irrational number between -2 and -1 would be
`(-\pi )/(2)`

A rational number between -2 and -1 would be -1.5

Explanation:

`(-\pi )/(2)` = -1.570796... This number does not have repeating decimals, patterns, and it isn't a terminating decimal. It is irrational.

-1.5 is a terminating decimal, therefore it is rational, as well as between -2 and -1.
