[plt-scheme] HtDP Exercise 25.5.3 - Very Quick Question

The exercise describes a problem solving process, and then instructs
the student to "repeat the process with epsilon/2 and then with
epsilon/4."

Here's a link: http://www.htdp.org/2003-09-26/Book/curriculum-Z-H-29.html#node_sec_23.5

Does that translate to "epsilon divided by 2 and 4" or "epsilon as 2
and 4?"

Thanks!
