Can someone explain how the solution got equations 3.9 and 3.10 in the challenge problems from module 1? I understand up to equation 3.8. Thanks in advance!

If you notice, the instructions right before 3.9 have a reference to the footnote, where they say they got the 1.25
In 3.10, they divide our deduced value by the given value (3.1/1.25) to get 0.4

Why do we divide to get the coefficient?
