I would guess that you would need to find the Least Common Multiple (LCM) of 99 and 24 first.
After listing out all of the multiples, you would have 792 be the LCM of 99 and 24. But since we need to find the integer value of n, in 99n (which means 99 x n), then we need to divide 792 by 99, which would be 8.
n = 8

Answer:
Step-by-step explanation:
The change of base formula is
so filling in our given:
(Note: you do not have to put the base of 10 in the change of base formula because the "normal" base for a log is 10 and that is how your calculator figures it.)
Do this on your calculator to get
Not sure how many decimal places you needed!
The second one because 1/4 times 3/3 equals 3/12
