Question

Identify the number as rational or irrational. Explain.

-√127

Answer 1

It's rational . You are asked to find the negative of sqrt127 not sqrt -127
So -sqrt127 would be -11.27

Answer 2

All numbers that can be written as an integer are rational numbers.

Answer 3

-11.27 is only an approximation
\[-\sqrt{127} \] Cannot be written as a ratio of two rational numbers
therefore -√127 is Irrational
