Respuesta:
1) [tex]-\frac{1}{2}[/tex]
2) 2
Explicación paso a paso:
1)
[tex](1-\frac{3}{4})-(2-\frac{5}{4})\\ (\frac{4-3}{4})-(\frac{8-5}{4})\\\frac{1}{4} -\frac{3}{4} \\-\frac{2}{4} = -\frac{1}{2}[/tex]
2)
[tex]\frac{5}{11}.(3.\frac{22}{15} )\\\frac{5}{11}.\frac{66}{15} = \frac{1}{1} . \frac{6}{3} = \frac{1}{1} . \frac{2}{1} \\\frac{2}{1} = 2[/tex]
