Final Answer:
10 blades of grass

──────────────────────────────────────

Explanation:
We are told that the grasshopper must eat half its body weight in grass each day.
Its body weight is 2 grams, so half of that is:
2 g ÷ 2 = 1 gram of grass per day.

Each blade of grass weighs 0.1 grams.
So to get 1 gram of grass, the grasshopper needs:
1 g ÷ 0.1 g per blade = 10 blades of grass.

That’s the answer: 10 blades of grass.
