Can you tell me if I answered these correctly? SCIENCE: How is the basic structure of living organisms different from that of non-living organisms? MY ANSWER: Living things need energy, nutrients, water and sunlight. Non Living things have no life at all. MATH: Explain how an estimate can help you decide where to place the decimal point? My ANSWER: Actually, I was not sure how to answer this question. Can someone help me? Thanks.

  Your first answer is correct. For the math problem, you can round to get an approximate number. For instance if you're multiplying 3.75 by 6.0423 -- multiply 4 * 6 = 24. That tells you that the whole number is around 24.
