Measurement problem

A box has 4 books inside weighs 5kg. The box weight 600g. What is the weight of each book?
First I convert the 5kg to 5000g because it will be easier. I convert 5kg to 5000g because 1kg = 1000g so 5kg = 5000g.

5000g - 600g = 4,400g

half of 4,400 is 2,200

half of 2,200 is 1,100g so one book weight 1,100g or 1.1kg
