Round the highest place means keeping the farther non-zero digit to the left, then rounding. Therefore, there should only be one non-zero digit in our final answer. The only answer choice that follows this <em>and</em> correctly rounds is ![\boxed{841\rightarrow 800}](https://tex.z-dn.net/?f=%5Cboxed%7B841%5Crightarrow%20800%7D)

There are 30 days in November. Therefore, the number of pages typed is equal to ![30\cdot 25=\boxed{750}](https://tex.z-dn.net/?f=30%5Ccdot%2025%3D%5Cboxed%7B750%7D)
We have to find the GCF of
![\frac{63}{81}](https://tex.z-dn.net/?f=%20%5Cfrac%7B63%7D%7B81%7D%20)
. The GCF of
![\frac{63}{81}](https://tex.z-dn.net/?f=%20%5Cfrac%7B63%7D%7B81%7D%20)
is 9.
