prima = 32
-----
108 sau 171
a doua= 6
---
1225 sau1285
a treia=43
---
461 sau 288
[tex] \frac{11}{36} +\frac{4}{27} +\frac{17}{108} = \frac{11}{108} + \frac{16}{108} +\frac{17}{108} = \frac{66}{108} = \frac{11}{18} [/tex]
[tex] \frac{1}{15} +\frac{2}{35} + \frac{3}{1225} = \frac{735}{11025} +\frac{490}{11025} + \frac{27}{11025} = \frac{1252}{11025} = 0.11356[/tex]
[tex] \frac{5}{ 2^{5}}+ \frac{7}{96} + \frac{31}{ 32* 3^{2} } = \frac{5}{32} + \frac{7}{96} + \frac{31}{32*9} = \frac{5}{32} + \frac{7}{96} + \frac{31}{288}= \frac{45}{288} +\frac{21}{288} + \frac{31}{288} = [/tex][tex]= \frac{97}{288} =0.336806[/tex]
