conversations.value: Can you explain how to solve this math problem: Uncle Ben has four horses. Each horse can consume five pounds of oats per meal. He feeds his horses twice a day. If one bag contains 50-pounds of oats,  how many bags of oats does he need to fed his horses for five days?

conversations.value: The four horses can consume 4 x 5 pounds = 20 pounds of oats per meal.
  Thus, they can consume 2 x 20 pounds = 40 pounds of oats a day.
  So, uncle Ben needs 5 x 40 pounds = 200 pounds of oats to fed his horses for five days.
  Therefore, uncle Ben needs 200/50 = 4 bags of oats.
