Horse Barn (Part 1) (Use estimation to solve multi-step word problems involving multiplication and division.)

MacDonald needs to buy grain for his four horses, each requiring at least 8 pounds. He estimates needing 5 bags, each containing 6 pounds. The video guides through calculating if his estimate is correct by multiplying the number of bags by the weight per bag and comparing it to the total grain needed for the horses. The analysis shows that MacDonald's estimate is insufficient, as the horses require more grain than the estimated bags provide.
