Salutare !

La inceput trebuie sa aflam paranteza

3/4 -2 ) 1/2 = 3/4 - 2/4 = 1/4

3/4 x 4/1 - 4/9 = 12/4 - 4/9 =9)  3 - 4/9 = 27/9 - 4/9 = 23/9

Answer 2

$\it \dfrac{3}{4}: \Big(\dfrac{3}{4}-\dfrac{^{2)}1}{\ 2}\Big)-\dfrac{4}{9}=\dfrac{3}{4}:\dfrac{1}{4}-\dfrac{4}{9}=\dfrac{3}{\not4}\cdot\dfrac{\not4}{1}-\dfrac{4}{9}=\dfrac{^{9)}3}{\ 1}-\dfrac{4}{9}=\dfrac{27-4}{9}=\dfrac{23}{9}$
