Answer 3

$P = \frac{23.1}{11.12} - \frac{25.1}{12.13} + \frac{27.1}{13.14} - \frac{29}{14.15} + \frac{31.1}{15.16} - \frac{33.1}{16.17} + \frac{35.1}{17.18} P = \frac{23}{11.12} - \frac{25}{12.13} + \frac{27}{13.14} - \frac{29}{14.15} + \frac{31}{15.16} - \frac{33}{16.17} + \frac{35}{17.18} P = \frac{11 + 12}{11.12} - \frac{12 + 13}{12.13} + \frac{13 + 14}{13.14} - \frac{14 + 15}{14.15} + \frac{15 + 16}{15.16} - \frac{16 + 17}{16.17} + \frac{17 + 18}{17.18} P = (\frac{1}{11} + \frac{1}{12}) - (\frac{1}{12} + \frac{1}{13}) + (\frac{1}{13} + \frac{1}{14}) - (\frac{1}{14} + \frac{1}{15}) + (\frac{1}{15} + \frac{1}{16}) - (\frac{1}{16} + \frac{1}{17}) + (\frac{1}{17} + \frac{1}{18}) P = \frac{1}{11} + \frac{1}{18} P = \frac{29}{198}$

Vậy $P = \frac{29}{198}$

Answer 4

$P = \frac{23.1}{11.12} - \frac{25.1}{12.13} + \frac{27.1}{13.14} - \frac{29}{14.15} + \frac{31.1}{15.16} - \frac{33.1}{16.17} + \frac{35.1}{17.18} P = \frac{23}{11.12} - \frac{25}{12.13} + \frac{27}{13.14} - \frac{29}{14.15} + \frac{31}{15.16} - \frac{33}{16.17} + \frac{35}{17.18} P = \frac{11 + 12}{11.12} - \frac{12 + 13}{12.13} + \frac{13 + 14}{13.14} - \frac{14 + 15}{14.15} + \frac{15 + 16}{15.16} - \frac{16 + 17}{16.17} + \frac{17 + 18}{17.18} P = (\frac{1}{11} + \frac{1}{12}) - (\frac{1}{12} + \frac{1}{13}) + (\frac{1}{13} + \frac{1}{14}) - (\frac{1}{14} + \frac{1}{15}) + (\frac{1}{15} + \frac{1}{16}) - (\frac{1}{16} + \frac{1}{17}) + (\frac{1}{17} + \frac{1}{18}) P = \frac{1}{11} + \frac{1}{18} P = \frac{29}{198}$

Vậy $P = \frac{29}{198}$
