​

Answer 1

Explicație pas cu pas:

$\left(5 \frac{2}{3} + 1.(5) - 2 \right) \div 15 \frac{2}{3} = \\ = \left(\frac{17}{3} + \frac{15 - 1}{9} - 2 \right) \div \frac{47}{3} \\ =  \left(\frac{51}{9} + \frac{14}{9} - \frac{18}{9} \right) \times \frac{3}{47} \\ = \frac{51 + 14 - 18}{9} \times \frac{3}{47} = \frac{47}{9} \times \frac{3}{47} \\ = \frac{1}{3}$
