Raspuns:

$2)1 \frac{1}{3} = \frac{1 \times 3 + 1}{3} = \frac{4}{3} = \frac{7}{3} - \frac{4}{3} = \frac{3}{3} (nr \: cautat)$

$3)\frac{3}{4} x = 6 = \frac{4}{3} \times \frac{3}{4} x = \frac{4}{3} \times 6 = x = 4 \times 2 = 8$

$1) \frac{1}{7} (x - 2.3) = \frac{5}{14} = x - 2.3 = \frac{5}{2} = x = \frac{5}{2} + 2.3 = x = \frac{24}{5} = 4.8$

$2)2.(3) = \frac{23 - 2}{9} = \frac{21}{9} = \frac{7}{3} = \frac{7}{3} + \frac{5}{3} = \frac{7 + 5}{3} = \frac{12}{3} = 4$ 5/3 este numarul
