Hey there!
[tex]\text{What is the smallest number?: -1,3,7,9,11}[/tex]
All numbers are positive except -1. If a number is negative, then that negative number will be less than a positive. All are positive and -1 is negative. Since that's the only negative, -1 is the smallest number.
[tex]-1\text{ is the smallest number.}[/tex]
Hope this helps!
