RESOLUCIÓN:
[tex]1) \: \: \: \: \: \frac{9}{4} - 1 = \frac{5}{4} = 1 \frac{1}{4} \\ \\2) \: \: \: \: \: 1 \frac{1}{4} - \frac{1}{3} = \frac{5}{4} - \frac{1}{3} = \frac{ 3\times 5 - 4 \times 1}{12} = \frac{11}{12} \\ \\3) \: \: \: \: \: \frac{11}{12} + 3 = \frac{47}{12} = 3 \frac{11}{12} \\ \\4) \: \: \: \: \: 3\frac{11}{12} \div - 3 = \frac{47}{36} = - 1 \frac{11}{36} [/tex]
