Answer :
The mixed fraction is express as :
[tex]a\frac{b}{c}=\frac{a\times c+b}{c}[/tex]The given expression is : 5 divide (-3 3/4)
First simplify : -3 3/4
[tex]\begin{gathered} 3\frac{3}{4}\text{ is express as :} \\ 3\frac{3}{4}\text{ =}\frac{3\times4+3}{4} \\ 3\frac{3}{4}=\frac{12+3}{4} \\ 3\frac{3}{4}=\frac{15}{4} \end{gathered}[/tex][tex]\begin{gathered} 5\text{ divide -3}\frac{3}{4}=5\text{ }\div\frac{(-15)}{4} \\ 5\text{ divide -3}\frac{3}{4}=5\times\frac{4}{(-15)} \\ 5\text{ divide -3}\frac{3}{4}=\frac{1\times4}{(-3)} \\ 5\text{ divide -3}\frac{3}{4}=-\frac{4}{3} \end{gathered}[/tex]Answer : -4/3
