2,3(6)=(236-23)/90=213/90=71/30
[tex]\dfrac{\dfrac{71}{30}}{\dfrac34}=\dfrac{71}{30}\cdot\dfrac43=\dfrac{142}{45}=3,1(5)[/tex]
[tex]\dfrac{\dfrac{71}{30}}{\dfrac34}=\dfrac{71}{30}\cdot\dfrac43=\dfrac{142}{45}=3,1(5)[/tex]
2,3(6)=2[tex] \frac{36-3}{90} [/tex]=[tex] \frac{90*2+33}{90} [/tex]=213/90
raportul este 213/90*4/3=142/45
raportul este 213/90*4/3=142/45
