Answer 1

Answer:

0.6

Step-by-step explanation:

Given :

Numerator is: {(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6)}

Denominator is: {(n) + (n + 1) + ... + (n + 11)}

To Find: Determine the fraction of total interest owed.

Solution :

Numerator is: {(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6)}

Since we are given that After the sixth month of a 12-month loan this becomes numerator .

So, put n = 6

Numerator = {(6 + 11) + (6 + 10) + (6 + 9) + (6 + 8) + (6 + 7) + (6 + 6)} = 87

Denominator : {(n) + (n + 1) + (n+2)+(n+3) +(n+4)+(n+5)+(n+6)+(n+7)+(n+8)+(n+9)+(n+10) + (n + 11)}

Put n =6

{(6) + (6 + 1) + (6+2)+(6+3) +(6+4)+(6+5)+(6+6)+(6+7)+(6+8)+(6+9)+(6+10) + (6+ 11)}

=138

Thus the fraction : $\frac{Numerator}{Denominator} =\frac{87}{138} =\frac{29}{46}=0.6$

Answer 2

Numerator is 57. denominator is 78 therefore, the fraction is numerator/denominator (to the nearest tenth) = 73.1%
