[tex]2\frac{3}{11}-1\frac{1}{10}=\frac{(2)(11)+3}{11}-\frac{(1)(10)+1}{10}[/tex]
[tex]2\frac{3}{11}-1\frac{1}{10}=\frac{24}{11}-\frac{11}{10}[/tex]
[tex]2\frac{3}{11}-1\frac{1}{10}=\frac{(24)(10)-(11)(11)}{(11)(10)}[/tex]
[tex]2\frac{3}{11}-1\frac{1}{10}=\frac{119}{110}[/tex]
La respuesta correcta es la c).
Enunciado 8:
[tex]4\frac{2}{3}+3\frac{1}{2}+2\frac{5}{6}=\frac{(4)(3)+2}{3}+\frac{(3)(2)+1}{2}+\frac{(2)(6)+5}{6}[/tex]
[tex]4\frac{2}{3}+3\frac{1}{2}+2\frac{5}{6}=\frac{14}{3}+\frac{7}{2}+\frac{17}{6}[/tex]
[tex]4\frac{2}{3}+3\frac{1}{2}+2\frac{5}{6}=\frac{(2)(14)+(3)(7)+(1)(17)}{6}[/tex]
[tex]4\frac{2}{3}+3\frac{1}{2}+2\frac{5}{6}=\frac{66}{6}[/tex]
[tex]4\frac{2}{3}+3\frac{1}{2}+2\frac{5}{6}=11[/tex]
