0,(34)-1,(25)=34/99-125-1/99=34/99-124/99=-90/99=10/11
0,0(5)+1,2(3)=5/90+123-12/90=5/90+111/90=116/90=58/45
-4,(3)+1,(5)= -[43-4]/9+15-1/9=-39/9+14/9=-25/9
-2,5+2,(5)-2,(5)=-2,5
-3,(8)+3,0(8)= -[38-3]/9+308-30/90=-35/9+278/90=-35*10+278/90=(-350+278)/90\=-72/90=-26/45
0,(34)-1,(25) = [tex] \frac{34}{9} - \frac{125}{9} = - \frac{91}{9} [/tex]
0,0(5) + 1,2(3)= [tex] \frac{5}{90} + \frac{123}{90} = \frac{118}{90} [/tex]
-4,(3) +1,(5) = [tex] - \frac{43}{9} + \frac{15}{9} = -\frac{28}{9} [/tex]
-2,5+2,(5)-2,(5) = [tex] -\frac{25}{10} + \frac{25}{9} - \frac{25}{9} = - \frac{25}{10} [/tex]
-3,(8) +3,0(8) =[tex]- \frac{38^1^0}{9}+ \frac{308}{90}= - \frac{380}{90} + \frac{308}{90}= - \frac{72}{90} [/tex]
