We have:
[tex]\sf\dfrac{5.5}{12}[/tex]
Convert to a denominator of 60, since there are 60 minutes in an hour.
[tex]\sf60\div12=5[/tex]
Multiply both the numerator and denominator by 5.
[tex]\sf5\times5.5=27.5[/tex]
[tex]\sf12\times5=60[/tex]
So we have:
[tex]\sf\dfrac{27.5}{60}[/tex]
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. :)
