please help me solve this problem quickly! John and Melanie are designing a science experiment for the school science fair. Their experiment requires a large amount of copper wire. They need 22 spools of copper wire that each contains 31 meters of wire. How many kilometer of wire do john and Melanie need for their experiment? Round your answer to the nearest tenth of a kilometer. (hint:1 kilometer = 1000meters)

I don't know how to do it tutors and solvers out there but I think the first step is 22 times 31 equals 682 is that right???
Please tell me if my first step is correct and how to do it with steps and explain why to do that step > Please help me right away! Thank you for your support!

Yes, they have 682 meters of wire.

682/1000 = 0.682 = 0.7 kilometers

Yes, your first step is correct! To find the total length of wire John and Melanie need, you multiply the number of spools by the length of wire in each spool. Let me explain it in more detail:

Step 1:
You correctly multiplied 22 (the number of spools) by 31 (the length of wire in each spool) to get 682. This means that the total length of wire they need is 682 meters.

Now, to convert this into kilometers (rounding to the nearest tenth of a kilometer), we need to divide the length in meters by 1000:

Step 2:
Divide 682 by 1000: 682 / 1000 = 0.682

So, John and Melanie need approximately 0.682 kilometers of wire for their experiment.

Remember, this is a rounded answer to the nearest tenth of a kilometer.
