2 11/12÷(²⁾5/4-3/8)+2/9=

(2×12+11)/12:(10/8-3/8)+2/9=

35/12:7/8+2/9=

35/12×8/7+2/9=

³⁾10/3+2/9=

30/9+2/9=

32/9=3 intregi 5/9

[tex]2 \times \frac{11}{12} \div ( \frac{5}{4} - \frac{3}{8} ) + \frac{2}{9} = \\ \frac{11}{6} \div \frac{10 - 3}{8} + \frac{2}{9} = \frac{11}{6} \times \frac{8}{7} + \frac{2}{9} = \\ = \frac{11}{3} \times \frac{4}{7} + \frac{2}{9} = \\ = \frac{44}{21} + \frac{2}{9} = \frac{132 + 14}{63} = \frac{146}{63} [/tex]

Baftă!
