Answer 1

$\frac{18}{24} \times \frac{32}{21} = \frac{3}{4} \times \frac{32}{21} = \frac{8}{7}$

$4 \times \frac{7}{90} \times \frac{50}{35 } = 2 \times \frac{1}{45} \times \frac{50}{5} = \\ \\ 2 \times \frac{1}{9} \times 2 = \frac{4}{9}$

$\frac{2}{40} \times \frac{35}{9} \times \frac{60}{15} = \frac{1}{20} \times \frac{35}{9} \times 4 = \\ \\ \frac{1}{5} \times \frac{35}{9} = \frac{7}{9}$
