Respuesta:

1).

[tex]3\frac{1}{2} + 7 \frac{1}{3} \\ \\ \frac{7}{2} + \frac{22}{3} = \frac{21 + 44}{6} = \frac{65}{6} [/tex]

2)

[tex] a= 3 \frac{2}{4} + \frac{1}{4} = \frac{14}{4} + \frac{1}{4} = \frac{15}{4} \\ \\ b = 1 \frac{1}{4} = \frac{5}{4} \\ \\ a + b = \frac{15}{4} + \frac{5}{4} = \frac{20}{4} = 5[/tex]

3)

[tex]a \times b = \frac{3}{3} \times \frac{3}{5} \times \frac{5}{2} \times \frac{3}{2} \times \frac{1}{9} \times \frac{18}{5} = \frac{3}{10} [/tex]

4)

[tex](2 \frac{1}{3} )(3 \frac{1}{4} )(1 \frac{1}{3} ) = \frac{7}{3} \times \frac{13}{4} \times \frac{4}{3} = [/tex]
