step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
