[tex]\boxed{\boxed{\bf \frac{310}{3} }}[/tex]
Explicație pas cu pas:
[tex]\mathbf{2 \frac{1}{3} + (( \frac{3}{2} + \frac{4}{9} \times 2 \frac{1}{4} ) \div \frac{1}{9} + \frac{11}{4} ) \div \frac{1}{4} }[/tex]
[tex]\mathbf{ \frac{2 \times 3 + 1}{3} + (( \frac{3}{2} + \frac{4}{9} \times \frac{2 \times 4 + 1}{4} ) \div \frac{1}{9} + \frac{11}{4} ) \div \frac{1}{4} }[/tex]
[tex]\mathbf{ \frac{6 + 1}{3} + (( \frac{3}{2} + \frac{1}{9} \times (8 + 1)) \times 9 + \frac{11}{4} ) \times 4}[/tex]
[tex]\mathbf{ \frac{7}{3} + (( \frac{3}{2} + \frac{1}{9} \times 9) \times 9 + \frac{11}{4} ) \times 4}[/tex]
[tex]\mathbf{ \frac{7}{ 3 } + (( \frac{3}{2} + 1) \times 9 + \frac{11}{4} ) \times 4}[/tex]
[tex]\mathbf{ \frac{7}{3} + ( \frac{5}{2} \times 9 + \frac{11}{4}) \times 4 }[/tex]
[tex]\mathbf{ \frac{7}{3} + ( \frac{45}{2} + \frac{11}{4} ) \times 4 }[/tex]
[tex]\mathbf{ \frac{7}{3} + \frac{101}{4} \times 4 = \frac{7}{3} + 101 }[/tex]
[tex]\mathbf{ \frac{7 + 303}{3} = \boxed{\boxed{\bf \frac{310}{ 3} }}}[/tex]
Bafta ! :)
