Answer 2

Step-by-step explanation:

$(3 \frac{2}{5} + 2 \frac{1}{10} ) \div (4 \frac{3}{5} - 3 \frac{3}{10} ) \\ \\ ( \frac{17}{5} + \frac{21}{10} )\div (\frac{23}{5} - \frac{33}{10} ) \\ \\ \frac{34 + 21}{10} \div \frac{46 - 33}{10} \\ \\ \frac{55}{10} \div \frac{13}{10} \\ \frac{55}{10} \times \frac{10}{13} \\ \\ \frac{55}{13} \\ 4 \frac{3}{13}$
