a)
[tex]-5 × (-0,25) × 0,2 = 1,25 × 0,2= 0,25[/tex]
b)
[tex] \frac{1}{3} \times ( - \frac{4}{5} ) \times 15 = ( - \frac{4}{5}) \times \frac{15}{1} = - 4[/tex]
c)
[tex]( - 6) \times ( - 2 \frac{1}{2} ) \times \frac{4}{3} \times ( - 0.1) = ( - \frac{6}{1} ) \times ( - \frac{5}{2} ) \times \frac{4}{3} \times ( - \frac{1}{10} ) = 15 \times (-\frac{2}{15} ) = -2[/tex]
d)
[tex]6 \times ( - 0.75) \times ( - \frac{1}{3} ) \times 0.4 = ( - 4.5) \times ( - \frac{1}{3} ) \times \frac{4}{10 } = ( - 4.5) \times ( - \frac{4}{30} )= ( - \frac{45}{10} ) \times ( - \frac{4}{30} ) = \frac{6}{10} = 0.6= 3/5[/tex]
Mam nadzieję, że pomogłam :)
