    450,000,000mg

    Step-by-step explanation:

    1kg = 1000g

    1g = 1000mg

    Let's find out how many mg is 1 kg. In order to do so, multiply 1000 by 1000.

    Therefore, 1kg = 1000 (1000) mg = 1 000 000 mg

    Now, let's solve the question by multiplying 1,000,000 by 450 since 450kg = 450 (1 kg).

    450kg = 450 (1 000 000) mg = 450 000 000 mg

    This is also equivalent to 4.50 * 10^8 mg.
