Respuesta:

$\frac{7}{39} +\frac{11}{26} +\frac{2}{3} +\frac{8}{9}$$=\frac{611}{1014}+\frac{42}{27}=\frac{16497+42588}{27378}=\frac{59085}{27378}=2.15$

$\frac{1}{3}+\frac{1}{9} +\frac{1}{18} +\frac{7}{24} +\frac{11}{30}$$=\frac{12}{27}+\frac{220}{432}+\frac{11}{30}$$=\frac{11124}{11664}+\frac{11}{30}$$=\frac{478224}{349920}=1.36$

$\frac{7}{25} +\frac{8}{105} +\frac{9}{21} +\frac{11}{50} +\frac{1}{63}$$=\frac{935}{2625}+\frac{681}{1050}+\frac{1}{63}$$=\frac{2769375}{2756250}+\frac{1}{63}=$$\frac{176400000}{173643750}=1.01$

$\frac{19}{18} +\frac{61}{72} +\frac{13}{216} +\frac{1}{10} +\frac{13}{5}$$=\frac{2466}{1296}+\frac{346}{2160}+\frac{13}{5}$$=\frac{5774976}{10800}+\frac{13}{50}=\frac{288889200}{540000}$$=534.98$

$\frac{1}{324}+\frac{1}{162} +\frac{5}{108} +\frac{1}{14} +\frac{1}{21}$$=\frac{486}{52488}+\frac{178}{1512}+\frac{1}{21}=\frac{10077696}{79361856}+\frac{1}{21}=\frac{290993472}{1666598976}$$=0.17$

$\frac{1}{900} +\frac{101}{300} +\frac{13}{60} +\frac{17}{45}+\frac{19}{54}=$$\frac{91200}{270000}+\frac{1605}{2700}+\frac{19}{54}$$=\frac{679590000}{729000000}+\frac{19}{54}$$=\frac{50548860000}{39366000000}=1.28$
