Question

calculati {0,5+[0,(7) -1/3] * 4,5} * 4

Answer 1

[tex]\{0,5+[0,(7)-\frac{1}{3}]\cdot 4,5\} \cdot4=\\ \\ \{\frac{1}{2}+[\frac{7}{9}-\frac{1}{3}]\cdot\frac{9}{2}\}\cdot4=\\ \\ (\frac{1}{2}+\frac{4}{9}\cdot\frac{9}{2})\cdot 4=\\ \\ (\frac{1}{2}+2)\cdot4=\\ \\ \frac{5}{2}\cdot 4=\boxed{10}[/tex]
