A student measures the mass of a book as 12,321g. What is the book's mass in kg?

to convert to kg
1kg=1000g 
thanks, buti don't understand where to put the decimal in the answer!

Hm..the decimal point?
lets see...
12,321g (1kg/1000g)= 12.321kg 
You can divide 12,321 by 1,000 on your calculator. What do you get?
Or  since you're dividing by 1,000 which has has 3 zeroes, move the decimal point 3 places to the left.
Does your answer make sense? Would you expect the book to have more or less grams than kilograms?
