[0,(6)+5,(6)]×(0,6+0,6:2)

Answer 1

Răspuns:

Explicație pas cu pas:

$\Big[0.(6) + 5.(6)\Big] \times (0.6 + 0.6 \div 2)$

$= \Big(\frac{6}{9} + \frac{56 - 5}{9} \Big) \times (0.6 + 0.3)$

$= \Big( \frac{6}{9} + \frac{51}{9} \Big) \times 0.9$

$= \frac{ 57 {}^{(3} }{9} \times \frac{9}{10}$

$= \frac{19}{3} \times \frac{9}{10} = \frac{171 {}^{(3} }{30} = \boxed{ \frac{57}{10} }$
