Explicación paso a paso:

I

a. $\frac{11}{12} -\frac{13}{18} = \frac{33-26}{36} =\frac{7}{36}$

b.$\frac{32}{49} -\frac{12}{21} =\frac{96-84}{147}= \frac{12}{147}= \frac{4}{49}$

c.$\frac{12}{15} -\frac{13}{20} =\frac{48-39}{60} =\frac{9}{60} =\frac{3}{20}$

d.$\frac{23}{22} -\frac{10}{11} =\frac{23-20}{22} =\frac{3}{23}$

e.$\frac{47}{34} -\frac{21}{17} =\frac{47-42}{34} =\frac{5}{34}$

II

a.$\frac{13}{10} +\frac{13}{15} =\frac{39+26}{30} =\frac{65}{30} =\frac{13}{6}$

b.$\frac{23}{24} +\frac{13}{19} =\frac{69+52}{72} =\frac{121}{72}$

c.$\frac{10}{12} +\frac{12}{16} =\frac{40+36}{48} =\frac{19}{12}$

d.$\frac{11}{10} +\frac{11}{14} =\frac{77+55}{70} =\frac{132}{70} =\frac{66}{35}$

e.$\frac{17}{10} +\frac{17}{20} =\frac{34+17}{20} =\frac{51}{20}$
