Answer 1

$Total\ apple=15 \frac{9}{10}kg= \frac{159}{10}kg \\ \\ It\ is \ to\ be\ divided\ among\ three\ people. \\ \\ each\ will\ get= \frac{ \frac{159}{10} }{3} = \frac{159}{10*3} = \frac{159}{30} =5 \frac{9}{30}kg=5 \frac{3}{10}kg$

So each will get $5 \frac{3}{10} kg$ of apples.

Answer 2

Total wt of apple is 15 9/10= 159/10
The apples are equally divided between three friends
Each of them will get (159/10)/3 kg
                               =  159/30
                               = 53/10
                               = 5 3/10. 
Each one of them would get  5 3/10 kg of apple.
