Answer 2

$\frac{390}{3250} \times 100 \\ \\ = \frac{39}{325} \times 100 \\ \\ = \frac{39}{65} \times 20 \\ \\ = \frac{3}{5} \times 20 \\ \\ = 12$

$\frac{5.5}{62.5} \times 100 \\ \\ = \frac{55}{625} \times 100 \\ \\ \frac{11}{125} \times 100 \\ \\ = \frac{11}{5} \times 4 \\ \\ = \frac{44}{5} \\ \\ = \frac{44}{5} \times \frac{2}{2} \\ \\ = 8.8$

hope it helps
