My question is: Dulce's father has eight orange trees on his farm. If each tree has 200 fruits and Dulce picks 2/5 of the oranges from each tree, calculate the total number of fruits remaining in all the trees. Your thoughts:
The total number of oranges in all the trees before Dulce picked any is 8 trees * 200 oranges / tree = 1600 oranges. If each orange tree has 200 oranges, and Dulce picks 2 / 5 of each tree's oranges, she picks 2 / 5 * 200 oranges = 80 oranges. Since the total number of orange trees is eight, Dulce picked 8 trees * 80 oranges / tree = 640 oranges from all the trees. After picking 640 oranges from the trees, the total number of oranges remaining became 1600 oranges - 640 oranges = 960 oranges. The final answer: 960.
