Answer:
for every hour she reads 6 chapters (1/6)
Explanation:
we know she reads 36 chapters in 6 hours, so we can make that a fraction : lets do 6/36 (it could also be 36/6 but im going to do 6/36)
if you divide both 6 and 36 by 6, you can simplify the fraction since 6 goes into both numbers evenly.
6/36 divided by 6/6 = 1/6
so the rate would be 1/6
