Rearrange:
[tex] \frac{3}{8} [/tex]-[tex] \frac{3}{8} [/tex]+[tex] \frac{5}{4} [/tex]-[tex] \frac{4}{5} [/tex]
0+[tex] \frac{5}{4} [/tex]-[tex] \frac{4}{5} [/tex]
We need the same denominator in order to subtract
[tex] \frac{5}{4}[/tex]×([tex] \frac{5}{5} [/tex]) - [tex] \frac{4}{5} [/tex]×([tex] \frac{4}{4} [/tex])
[tex] \frac{25}{20} [/tex]-[tex] \frac{16}{20} [/tex]
[tex] \frac{9}{20} [/tex]
Final Answer: [tex] \frac{9}{20} [/tex]
