a)
[tex]5 \frac{2}{3} \times 1.5 = \frac{17}{3} \times 1 \frac{5}{10} = \frac{17}{3} \times \frac{15}{10} = \frac{17}{1} \times \frac{5}{10} = \frac{85}{10} = 8.5[/tex]
b)
[tex] \frac{6}{25} \div 0.6 = \frac{6}{25} \div \frac{6}{10} = \frac{6}{25} \times \frac{10}{6} = \frac{1}{5} \times \frac{2}{1} = \frac{2}{5} [/tex]
c)
[tex]4 \frac{2}{3} \times 0.0006 = \frac{14}{3} \times \frac{6}{10000} = \frac{7}{1} \times \frac{2}{5000} = \frac{14}{5000} = \frac{7}{2500} [/tex]
d)
[tex]0.14 \div \frac{21}{25} = \frac{14}{100} \times \frac{25}{21} = \frac{2}{4} \times \frac{1}{3} = \frac{2}{8} = \frac{1}{4} [/tex]
Myślę że pomogłem ;)
