Explicație pas cu pas:
2,(3)=23-2/9=21/9=7/3
3,(4)=34-3/9=31/9
7/3+31/9=21/9+31/9=52/9
[tex]2.(3) + 3.(4) = [/tex]
[tex] = 2 \frac{3}{9} + 3 \frac{4}{9} = [/tex]
[tex] = \frac{2 \times 9 + 3}{9} + \frac{3 \times 9 + 4}{9} = [/tex]
[tex] = \frac{21}{9} + \frac{31}{9} = [/tex]
[tex] = \frac{52}{9} [/tex]
