svlad2 [7]
To find the miles Michael rode, we can simply add up the miles he rode for both day:

2 \frac{2}{3}   + 1 \frac{5}{6}  \\  =  \frac{2 + 2 \times 3}{3}  +  \frac{5 + 6}{6}  \\  =  \frac{8 \times 2}{3 \times 2}  +  \frac{11}{6}  \\  =  \frac{16 + 11}{6}  \\  =  \frac{27}{6}  \\  = 4 \frac{3}{6}  \\  = 4 \frac{1}{2}
Therefore the answer is 4 1/2 miles.

Hope it helps!
