Use the si prefixes in table 3 of this chapter to convert these hypothetical units of measure into appropriate quantities: a. 10 rations b. 2000 mockingbirds c. 10−6 phones d. 10−9 goats e. 1018 miners

Sadly, I haven't read the chapter, and I can't see Table 3.
But I've seen this fun question before, so instead of reporting
the question for incomplete content, I'm going to answer it
and take your points.

a).  one decaration

b).  two kilomockingbirds

c).  one microphone

d).  one nanogoat

e).  one examiner 

By the way ... perhaps it hadn't occurred to you, but YOU could have
easily answered these completely on your own.  All you'd need to do 
is take a look at Table 3 in the latest chapter of your Physics book !

Wavelength divides in half and speed stays the same.
