Answer:
[tex]2 \frac{13}{20} \\ [/tex]
Step-by-step explanation:
[tex]3 \frac{1}{5} + 75\% - 1 \frac{3}{10} \\ \frac{16}{5} + \frac{75}{100} - \frac{13}{10} \\ \frac{16}{5} + \frac{3}{4} - \frac{13}{10} \\ \frac{16 \times 4}{5 \times 4} + \frac{3 \times 5}{4 \times 5} - \frac{13 \times 2}{10 \times 2} \\ \frac{64 + 15 - 26}{20} \\ \frac{53}{20} \\ 2 \frac{13}{20} \\ [/tex]
