Acoconut tree has 12 coconuts on it. if 25% of the coconuts fell to the ground, how many fell to the ground?

Three coconuts fell onto the ground. 25% is equal to 0.25. To find the percent of a number, just multiply the percent by the number. 0.25 x 12 is 3.

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)
