Explicație pas cu pas:

$\frac{16}{25} \cdot \frac{21}{5} \cdot \frac{5}{32} \cdot \frac{75}{14} = \frac{16 \times 21 \times 5 \times 75}{25 \times 5 \times 32 \times 14}$

$= \frac{16 \times 21 \times 75}{25 \times 32 \times 14} = \frac{2 \times 21 \times 3}{4 \times 14} = \frac{63}{28} =\frac{9}{4}$
