Answer 1

$\huge\frac{9}{9} + \frac{4}{9} - \frac{2}{9} + \frac{1}{9} = \\ \\ \huge = \frac{9 + 4 - 2 + 1}{9} = \\ \\ \huge = \frac{13 - 2 + 1}{9} = \\ \\ \huge = \frac{11 + 1}{9} = \frac{12}{9} {}^{(3} = \\ \\ \huge = \boxed{\frac{4}{3} }$

Answer 2

Bună! ✨

$\frac{ 9 }{ 9 } + \frac{ 4 }{ 9 } - \frac{ 2 }{ 9 } + \frac{ 1 }{ 9 } \\ \\ \frac{9+4}{9}-\frac{2}{9}+\frac{1}{9} \\ \\ \frac{13}{9}-\frac{2}{9}+\frac{1}{9} \\ \\ \frac{13-2}{9}+\frac{1}{9} \\ \\ \frac{11}{9}+\frac{1}{9} \\ \\ \frac{11+1}{9} \\ \\ \frac{12}{9} \\ \\ \boxed{\frac {4} {3}}$

✔️ Succes! ✔️
