Question

Calculati 5/6+0,(3):(0,5-3/4:3)

Answer 1

Explicație pas cu pas:

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