Answer 4

(\(\frac{1}{8}\)+ \(\frac{1}{24}\)) + (\(\frac{1}{9}+\frac{1}{18}\)) + \(\left(\frac{1}{10}+\frac{1}{15}\right)\)+ \(\left(\frac{1}{7}+\frac{1}{14}+\frac{1}{28}\right)\)+ \(\left(\frac{1}{11}+\frac{1}{22}+\frac{1}{33}\right)\)+ \(\frac{1}{12}\)=

\(\frac{1}{6}\)+ \(\frac{1}{6}\)+ \(\frac{1}{6}\)+ \(\frac{1}{4}\)+ \(\frac{1}{6}\)+ \(\frac{1}{12}\)= \(\frac{4}{6}\)+ \(\left(\frac{1}{4}+\frac{1}{12}\right)\)= \(\frac{2}{3}\)+ \(\frac{1}{3}\)=1
