Question

for a classroom assignment, ashley needs to estimate the weight of her cheese sandwich. which would be the most reasonable estimate?

200 grams
3 kilograms
10 kilograms
300 milligrams

Explanation:

Analyze the physical scale of each metric unit

• \(300\text{ milligrams} = 0.3\text{ grams}\) (extremely light, like a postage stamp or a pinch of salt)
• \(200\text{ grams}\) (typical weight of a small meal, apple, or sandwich)
• \(3\text{ kilograms} = 3000\text{ grams}\) (heavy, like a laptop or a small newborn baby)
• \(10\text{ kilograms} = 10000\text{ grams}\) (very heavy, like a large watermelon or a medium-sized dog)

Evaluate the options for a cheese sandwich

• A standard cheese sandwich consists of bread, cheese, and spreads, typically weighing between \(150\text{ g}\) and \(250\text{ g}\).
• Therefore, \(200\text{ grams}\) is the only reasonable estimate.

Answer:

• 200 grams (Correct answer)
• 3 kilograms
• 10 kilograms
• 300 milligrams
