Odpowiedź :
[tex]-5 + \frac{2}{11} = -4\frac{11}{11}+\frac{2}{11}=-4\frac{9}{11}\\\\6-8,8 = -2,8\\\\-3+(-4,5) = -3-4,5 = -7,5\\\\-2-(-1\frac{1}{4})=-2\frac{4}{4}+1\frac{1}{4}=-1[/tex]
Odpowiedź:
[tex] - 5 + \frac{2}{11} = ( - 4 \frac{11}{11} ) + \frac{2}{11} = ( - 4 \frac{9}{11} [/tex]
[tex]6 - 8.8 = 5 \frac{10}{10} - 8 \frac{8}{10} = ( - 3 \frac{2}{10} )[/tex]
