If the ratio of fast readers to slow reader is 9 to 5, and there are 4,716 fast readers, how many slow readers are there?
These given values will be used in proportions to solve the problem:
fast_one = 9
slow_one = 5
fast_two = 4716
slow_two = ?
You can rewrite a ratio of 9 fast readers to 5 slow readers as a proportion: 9/5
Now, set this equal to the proportion of fast to slow readers using the new number of fast readers.
We will be solving for slow_two.
(9)*(slow_two) = (4716)*(5)
slow_two=2620 slow readers
