Earle is correct. These expressions both represent the opposite of m.
1) Since rational numbers are those that can be written as a ratio like:
[tex]\frac{a}{b}[/tex]
2) In this case, since m is a rational number, let's test it
[tex]\begin{gathered} m=\frac{3}{5} \\ \frac{3}{5}\times-1=-\frac{3}{5} \\ \frac{3}{5}\colon\text{ -1= -}\frac{3}{5} \end{gathered}[/tex]
So, as we can see, for m in Q, Earle is correct.
Earle is correct. These expressions both represent the opposite of m.
