1)

$0.8 \times \frac{7}{12} = \frac{8}{10} \times \frac{7}{12} = \frac{4}{5} \times \frac{7}{12} = \frac{7}{15}$

2)

$1\frac{2}{3} \times 0.6 = \frac{5}{3} \times \frac{6}{10} = \frac{5}{3} \times \frac{3}{5} = 1$

3)

$1.25 \times \frac{32}{45} = \frac{125}{100} \times \frac{32}{45} = \frac{5}{4} \times \frac{32}{45} = \frac{8}{9}$

4)

$4.5 \times 3 \frac{1}{3} = \frac{45}{10} \times \frac{10}{3} = 15$
