We have:

\(\sf\dfrac{5.5}{12}\)

Convert to a denominator of 60, since there are 60 minutes in an hour.

\(\sf60\div12=5\)

Multiply both the numerator and denominator by 5.

\(\sf5\times5.5=27.5\)

\(\sf12\times5=60\)

So we have:

\(\sf\dfrac{27.5}{60}\)

Therefore Carrie read at a rate of 27.5 pages per hour.

You can divide 12 by 5 1/2, which is approximately 2.18, and you can multiply that to 60. You multiply it to 60 because there are 60 minutes in an hour, which equals about 130.9. :)
