How do I solve -6> (0r equal to) -0.6?

-6<-0.6<0

-6 ≥ -0.6 (wrong statement)

It should be:
-6 < -0.6

you do not have any variable
just compare the 2 numbers
-6 is less than -0.6 and not greater than

what is to solve? there is no variable.

-6 >= -0.6

you dont have variables, you just need to compare these numbers. to make things easy, multiply by -1 as :

6< 0.6

Since 6 is greater than 0.6, this is false and so is the original inequality
