Final answer:
This problem asks to determine the fraction of total interest owed after the fourth month of a 12-month loan.
Step-by-step explanation:
The given problem asks to determine the fraction of total interest owed after the fourth month of a 12-month loan. The numerator is (n¹¹)(n¹⁰)(n)(n), and the denominator is (n)(n¹)...(n) = 78. Therefore, the fraction is numerator/denominator (to the nearest tenth).
To solve this problem, we need more information about the value of 'n' and the interest rate of the loan.
