If each tree has 200 fruits, then the total number of fruits on all the trees is 8 trees × 200 fruits/tree = 1600 fruits.
If Dulce picks 2/5 of the oranges from each tree, she picks 2/5 × 200 = 80 oranges from each tree.
The total number of oranges she picks from all the trees is 8 trees × 80 oranges/tree = 640 oranges.
Therefore, the total number of fruits remaining in all the trees is 1600 fruits - 640 oranges = 960 fruits.
#### 960
