Please help me with the following problems:

3. Choose the more precise measurement.

6 cm or 2.5 cm

I think it is 2.5 cm. Is this correct?

7. Choose the less precise measurement and explain why it is less precise.

2.8 mm or 3.79 mm

I think the answer is 3.79 mm. Is this correct?

10. Find each sum or difference. Round to the place value of the less precise measurement.

7 cm – 4.4 cm

A. 11 cm

B. 10 cm

C. 3 cm

D. 2.6 cm

I think the answer is C. Is this correct?

Please help me by checking my answers. Any help will be again appreciate!! :)

3. is 2.5 cm, I finally figured it out.

7. is 3.79 mm, I finally figured that one out as well.

For 10, I just need help on still, so can someone please check my answer for it.

Actually, for 7, I meant to say 2.8 mm. I realized my mistake for it.

Never-mind!!! I got all of them correct!!! So, I don't need anyone to check any of them anymore. :D

Let's go through each question one by one and find the correct answers:

3. To choose the more precise measurement, we need to look at the number of decimal places. In this case, 6 cm has no decimal places, while 2.5 cm has one decimal place. The measurement with more decimal places is the more precise one. So, you are correct that 2.5 cm is more precise than 6 cm.

7. To choose the less precise measurement, we again need to look at the number of decimal places. In this case, 2.8 mm has one decimal place, while 3.79 mm has two decimal places. The measurement with fewer decimal places is the less precise one. So, you are correct that 2.8 mm is less precise than 3.79 mm.

10. To find the sum or difference and round to the place value of the less precise measurement, we need to consider the decimal places again. In this case, both measurements have one decimal place. So, we can simply subtract the numbers: 7 cm - 4.4 cm = 2.6 cm. Therefore, the correct answer is D.

Based on your explanations, it seems that you have correctly chosen the more precise measurement (2.5 cm), the less precise measurement (2.8 mm), and the correct sum or difference (2.6 cm). Good job!
