Answer:

Step-by-step explanation:

Morning: $4\frac{7}{8} +1\frac{2}{3} =\frac{39}{8} +\frac{5}{3} =\frac{117}{24} +\frac{40}{24}=\frac{157}{24}$

Afternoon: $3\frac{5}{6} +2\frac{7}{12} =\frac{23}{6} +\frac{31}{12} =\frac{92}{24} +\frac{62}{24}=\frac{154}{24}$

Therefore, the hiker's hiked $\frac{3}{24}$ more in the morning than in the afternoon.
