One thousand one hundred twenty-eight and seven-tenths metres equals how many kilometres?
First, let’s think, how many metres are in a kilometer? The answer is one thousand; there’re one thousand metres for every kilometer. If it takes one thousand metres to equal one kilometer and we have one thousand one hundred twenty-eight and seven-tenths metres, how we figure out exactly how many kilometres we have.
The answer is to divide by one thousand. To divide by one thousand, I’ll move my decimal point three places to the left. One thousand one hundred twenty-eight and seven-tenths divided by one thousand equals one point one two eight seven. One thousand one hundred twenty-eight and seven-tenths metres is a little bit larger than one kilometer; it’s one point one two eight seven kilometres.
