Vă rooog.​

Answer 1

Răspuns:

5/6+0,(3)÷(0,5-3/4÷3)=

5/6+3/9:(5/10-3/4×1/3)=

5/6+3/9:(²⁾1/2-1/4)=

5/6+3/9:(2/4-1/4)=

5/6+3/9:1/4=

5/6+(3/9)⁽³×4/1-

5/6+1/3×4=

5/6+²⁾4/3=

5/6+8/6=

13/6=2,1(6)

Answer 2

Explicație pas cu pas:

$\frac{5}{6} + 0.(3) : \Big(0.5 - \frac{3}{4} : 3\Big) = \\ = \frac{5}{6} + \frac{3}{9} : \Big( \frac{1}{2} - \frac{3}{4} \times \frac{1}{3} \Big) = \frac{5}{6} + \frac{1}{3} : \Big( \frac{^{2)} 1}{2} - \frac{1}{4} \Big) \\ = \frac{5}{6} + \frac{1}{3} : \frac{2 - 1}{4} = \frac{5}{6} + \frac{3}{9} : \frac{1}{4} = \frac{5}{6} + \frac{1}{3} \times 4 \\ = \frac{5}{6} + \frac{^{2)} 4}{3} = \frac{5 + 8}{6} = \frac{13}{6} = 2 \frac{1}{6} = 2.1(6)$
