Answer 1

Răspuns:

$\displaystyle \frac{27}{14}$

Explicație pas cu pas:

$\displaystyle \\2-\frac{1}{3} \div 4\frac{2}{3} = 2 - \frac{1}{3} \div \frac{4 \times 3 + 2}{3} \\ \\ \\= 2 - \frac{1}{3} \div \frac{14}{3} \\ \\ \\= 2 - \frac{1}{\not 3} \cdot \frac{\not 3}{14} \\ \\ \\= 2 - \frac{1}{14} \\ \\ \\= \frac{28}{14} - \frac{1}{14} \\ \\ \\\boxed{= \frac{27}{14}}$

Answer 2

4 întregi si 2/3 face 14/3
Exercițiul devine:
2-1/3:14/3=2-1/3•3/14=2-1/14=28/14-1/14
=27/14
