Răspuns:
[tex] = \frac{4}{3} \\ [/tex]
Explicație pas cu pas:
[tex]4 \times \Big( \frac{3}{4} - \frac{ {}^{2)} 1}{2} \Big) + 2,5 : \frac{15}{2} \\ [/tex]
[tex] = 4 \times \Big( \frac{3}{4} - \frac{2}{4} \Big) + \frac{25 {}^{(5} }{10} \times \frac{2}{15} \\ [/tex]
[tex] = \not4 \times \frac{1}{ \not4} + \frac{ \not5}{ \not2} \times \frac{ \not2}{ \not15} \\ [/tex]
[tex] = 1 + \frac{1}{3} = \frac{ {}^{3)} 1}{1} + \frac{1}{3} = \frac{3}{3} + \frac{1}{3} = \boxed{\frac{4}{3} } \\ [/tex]
