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
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?
thanks, buti don't understand where to put the decimal in the answer!
To convert grams to kilograms, you need to divide the mass in grams by 1000 since there are 1000 grams in a kilogram.
In this case, the mass of the book is 12,321 grams. So, you would divide 12,321 by 1000:
12,321g / 1000 = 12.321 kg
Therefore, the book's mass is 12.321 kg.
