A)
8+ \frac{1}{2} = \frac{17}{2} =8,5

b)
 \frac{24}{10} - \frac{3}{10} = \frac{21}{10} =2,1

c)
vou fazer esse = como+

 \frac{4}{10} + \frac{1}{2} + \frac{6}{10} = \frac{4+5+6}{10} = \frac{15}{10} =1,5

d)
 \frac{13}{10}  + \frac{1}{4} + \frac{7}{4} = \frac{26+5+35}{20} = \frac{66}{20} = \frac{33}{10} =3,3
