ANSWER
n = -49.6
EXPLANATION
Given that;
[tex]\text{ }\frac{\text{ n}}{\text{ 4}}\text{ = -12.4}[/tex]Follow the steps below to find the value of n
Step 1; Apply cross multiplication
[tex]\begin{gathered} \text{ }\frac{\text{ n}}{\text{ 4}}\text{ = -12.4} \\ \\ \text{ n = 4 }\times\text{ \lparen-12.4\rparen} \end{gathered}[/tex]Step 2; Multiply the values together
[tex]\begin{gathered} \text{ n = 4}\times\text{ \lparen-12.4\rparen} \\ \text{ n = -49.6} \end{gathered}[/tex]Therefore, the value of n = -49.6
