Let's add the fractions to determine how many miles Rami run:
[tex]\begin{gathered} \frac{3}{4}+\frac{7}{8}+\frac{5}{6}=\frac{24+28}{32}+\frac{5}{6} \\ =\frac{52}{32}+\frac{5}{6} \\ =\frac{13}{8}+\frac{5}{6} \\ =\frac{78+40}{48} \\ =\frac{118}{48} \\ =\frac{59}{24} \\ =2\frac{11}{24} \end{gathered}[/tex]Therefore Rami run 2 11/24 miles. (In decimal approximation this is 2.4583 miles)
