​

Answer 1

Răspuns:

$\frac{ 2 }{ 5 } + \frac{ 10 }{ 8 } \div \frac{ 4 }{ 25 }$

$\frac{2}{5}+\frac{10\times 25}{8\times 4}$

$\frac{2}{5}+\frac{5\times 25}{4\times 4}$

$\frac{2}{5}+\frac{125}{4\times 4}$

$\frac{2}{5}+\frac{125}{16}$

$\frac{32}{80}+\frac{625}{80}$

$\frac{32+625}{80}$

$\frac{657}{80}$

$\frac{3 ^ {2} \cdot 73}{2 ^ {4} \cdot 5} = 8\frac{17}{80} = 8.2125$
