Cześć!
[tex]a)( - 1 \frac{1}{5} ) \times 1 \frac{2}{3} = ( - \frac{6}{5} ) \times \frac{5}{3} = - \frac{30}{15} = - 2[/tex]
[tex]b)( - 10 \frac{2}{3} ) \div 1 \frac{7}{9} = ( - \frac{32}{3} ) \div \frac{16}{9} = ( - \frac{32}{3} ) \times \frac{9}{16} = - \frac{2}{1} \times \frac{3}{1} = - \frac{6}{1} = - 6[/tex]
Pozdrawiam!
