Answer 1

a

Answer 2

1000mg = 1gm

Answer 3

Let's convert both to the same unit and compare.
SInce the mass of the puppy is already in grams, let's convert the mass of a kitten to grams.

Answer 4

1 g = 1000 mg


That means
\( \dfrac{1~g}{1000~mg} = \dfrac{1000~mg}{1~g} =1\)

Since 450,000 mg has mg in the numnerator, and we want to cacel it, we multiply by the conversion factor that has mg in the denominator.

\(450,000~mg \times \dfrac{1~g}{1000~mg} = 450 ~g\)

Answer 5

Now you see that the puppy has a mass of 4,500 g, and a kitten has a mass of 450 g. Now it's easy to compare them.
