Can somebody just help me with the explanation? I don't know what to do for e,f, &g.

xishem · Answer

We can just use conversion factors:

e)$$0.675mg \times \frac{1g}{1000mg}=6.75 \times 10^{-4}g$$
f)$$462 \mu m \times \frac{1m}{10^6 \mu m} \times \frac{100cm}{1m}=.462m$$
I'm not sure what "h" is being referred to in b and g, though. Is there some context to the problem?

For g since the answer is expressed in meters/second.  However the numerator in the fraction doesn't show the units so that one is missing a key piece of info that's required to convert it.
