Answer: [tex]=-4\frac{7}{40}[/tex]
Step-by-step explanation:
[tex]3\frac{1}{5}+\left(-7\frac{3}{8}\right)[/tex]
[tex]=\frac{16}{5}+\left(-\frac{59}{8}\right)[/tex]
[tex]\frac{16}{5}+\left(-\frac{59}{8}\right)=\frac{16}{5}-\frac{59}{8}[/tex]
[tex]=\frac{128}{40}-\frac{295}{40}[/tex]
[tex]=\frac{128-295}{40}[/tex]
[tex]=\frac{-167}{40}[/tex]
[tex]=-4\frac{7}{40}[/tex]
