Explicație pas cu pas:
[tex] - \frac{4}{5} \times \Big( - \frac{15}{8} \Big) - \frac{7}{4} \\ [/tex]
[tex] = \frac{\not4}{\not5} \times \frac{\not15}{\not8} - \frac{7}{4} \\ [/tex]
[tex] = \frac{ {}^{2)} 3}{2} - \frac{7}{4} \\ [/tex]
[tex] = \frac{6}{4} - \frac{7}{4} = \frac{6 - 7}{4} = \boxed{ - \frac{1}{4} } \\ [/tex]
