Use the example above and determine the fraction of total interest owed. After the fourth month of a 12 month loan,

the numerator is: {(n +
) + (n +
) + (n +
) + (n +
} =
, and

the denominator is: {(n) + (n + 1) + ... + (n +
)} =
.

Therefore, the fraction is numerator/denominator (to the nearest tenth) =
