Hej!
[tex]8 \frac{1}{8} \div 3.9 = \frac{65}{8} \div \frac{39}{10} = \frac{65}{8} \times \frac{10}{39} = \frac{5}{4} \times \frac{5}{3} = \frac{25}{12} = 2 \frac{1}{12} [/tex]
[tex]0.045 \div ( - \frac{27}{40} ) = \frac{9}{200} \div ( - \frac{27}{40} ) = - \frac{9}{200} \times \frac{40}{27} = - \frac{1}{5} \times \frac{1}{3} = - \frac{1}{15} [/tex]
[tex] \frac{1}{2} \div 1.5 = \frac{1}{2} \div \frac{15}{10} = \frac{1}{2} \times \frac{10}{15} = \frac{5}{15} = \frac{1}{3} [/tex]
[tex] - 0.8 \div ( - \frac{2}{3} ) = - \frac{4}{5} \div ( - \frac{2}{3} ) = \frac{4}{5} \div \frac{2}{3} = \frac{2}{5} \times 3 = \frac{6}{5} = 1 \frac{1}{5} [/tex]
[tex] - 0.1 \div \frac{2}{5} = - \frac{1}{10} \times \frac{5}{2} = - \frac{1}{2} \times \frac{1}{2} = - \frac{1}{4} [/tex]
[tex] \frac{3}{4} \div 0.2 = \frac{3}{4} \div \frac{1}{5} = \frac{3}{4} \times \frac{5}{1} = \frac{15}{4} = 3 \frac{3}{4} [/tex]
[tex] \frac{1}{3} \div 0.25 = \frac{1}{3} \div \frac{1}{4} = \frac{1}{3} \times \frac{4}{1} = \frac{4}{3} = 1 \frac{1}{3} [/tex]
[tex] \frac{2}{3} \div ( - 0.6) = \frac{2}{3} \div \frac{3}{5} = \frac{2}{3} \times \frac{5}{3} = \frac{10}{9} = 1 \frac{1}{9} [/tex]
Gotowe!
