You can put this solution on YOUR website! In your first question, 17,540 m., to convert to km, move the decimal 3 places to the left. This would give you 17.54 km, which is b.
In your second questions, 65 mm = 6.5 cm because you move the decimal 1 place to the left.
In your last questions, I think you are correct, but I don't understand the second one.
For additional metric system resource, as well as other algebra topics that will helpful in your homeschool lessons, please see my own website. Do a "Bing" or a "Google" search for my last name "Rapalje". Near the top of the search list, look for "Rapalje Homepage." On my Homepage, look near the bottom of the page for the link "Topics from Geometry" and look for the link "Metric System".
