[tex] 2)8 \frac{1}{2} \times \frac{1}{8} = \frac{17}{2} \times \frac{1}{8} = \frac{17}{16} = 1 \frac{1}{16} [/tex]
[tex]3)0.85 \times \frac{2}{5} = \frac{85}{100} \times \frac{2}{5} = \frac{170}{500} = 0.34 \: l[/tex]
[tex] 4)1.2 \times 22.5 = \frac{12}{10} \times \frac{225}{10} = \frac{2.700}{100} = 27 \: km[/tex]
[tex]5)6.5 \times \frac{1}{3} = \frac{65}{10} \times \frac{1}{3} = \frac{65}{30} = 2.17 \: kg[/tex]
