Answer 1

$3 \frac{3}{5} \div 1 \frac{2}{3} = \frac{18 \times 3}{5 \times 5} = \frac{54}{25} = 2 \frac{4}{25} = 2.16$

$13 \frac{4}{5} \div 1 \frac{7}{23} = \frac{69 \times 23}{5 \times 3 0 } = \frac{23 \times 23}{5 \times 10} = \\ \frac{529}{50} = 10 \frac{29}{50} = 10.58$

$18 \frac{4}{5} \div \frac{3}{7} = \frac{94 \times 7}{5 \times 3} = \frac{658}{15} = 43 \frac{13}{15}$
