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) = %.

85.90%

Step-by-step explanation:

n = 1 in this problem, because the loan is calculated from the first month itself.

Numerator :

{(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6) + (n + 5)}

n + n + n + n + n + n + n = 7 (because n = 1)

7 + 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 = 67 (that's your numerator)

Denominator :

{(n) + (n + 1)... + (n + 11)}

add all of the n's together:

n + n + n + n + n + n + n + n + n + n + n + n = 12

Now you add that to the rest of the numbers:

12 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 = 78 (that's your denominator)

Percentage : Now for the percentage you just divide the numerator and the denominator and multiply the resultant by 100

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
