Answer:
5600000
Explanation:
There's 1000000 mg in one kg. Therefore you multiply 5.6 x 1000000 to get 5600000.
5.6 x 1000000
^ remember to move the decimal place over to the right once and then you take away a zero so you would be left with :
56 x 100000, this expression is easy to solve since you just need to count all the zeros and put that many zeros after 56 to get your final answer.
