[tex]a \: \\ 0.125 - \frac{1}{2} \div 1 \frac{1}{3} = 0.125 - \frac{1}{2} \times \frac{3}{4} = \\ = \frac{1}{8} - \frac{3}{8} = \\ = - \frac{2}{8} = - \frac{1}{4} [/tex]
[tex]b \\ - ( - \frac{2}{3} ) ^{2} - \frac{1}{3} = \\ = - \frac{4}{6} - \frac{2}{6} = - \frac{1}{3} [/tex]
[tex]c \\ 0.5 - \frac{2}{5} \times 1.25 = 0.5 - 0.4 \times 1.25 = \\ = 0.5 - 05 = 0[/tex]
[tex]d \\ \frac{4 + ( - 12)}{ - 2} + \frac{ {( - 3)}^{3} }{7 - ( - 2) } = \\ = \frac{ - 8}{ - 2} + \frac{ - 27}{9} = 4 + ( - 3) = 1[/tex]
proszę o naj :)
