First of all, you add 1/3 and 4/5, so you get:
\frac{1}{3} +  \frac{4}{5}

To add 2 fractions, they need to have the same denominator. Since 3 and 5 don't have a common factor, so you multiply 1/3 by 5, and 4/5 by 3, so you get:
\frac{1*5}{3*5} +  \frac{4*3}{5*3}
\frac{5}{15} +  \frac{12}{15}

Now, the two fractions got the same denominator, and you can add them by adding the numerators over the same denominator. (You don't add denominators in addition) so you get:
\frac{5+12}{15}
\frac{17}{15}

That's the sum of 1/3 + 4/5.

Now, they want the sum of the 2 fractions 7 times. So you multiply 17/15 by 7. And as you know, 7 = 7/1. So you get:
\frac{17}{15} *  \frac{7}{1}

In multiplication no need to have the same denominator. You multiply nominators by nominators and denominators by denominators. So you get:
\frac{17*7}{15*1}
\frac{119}{15}

Since 119 and 15 don't have a common factor, so they can't be simplified.
So, the answer is 119/15. 

Hope this Helps! :D

What you have to do first is to add \frac{1}{3} and \frac{4}{5},

<h2>Further Explanation</h2>

Therefore we have:

= \frac{1}{3} + \frac{4}{5}

= ( \frac{1}{3} + \frac{4}{5} ) / 15 (15 is the smallest number that divide both denominator also known as LCD)

= (5 x 1) + (3 x 4) / 15

= 5 + 12 / 15

= \frac{17}{15}

Therefore, the sum of \frac{1}{3} + \frac{4}{5} is \frac{17}{15}

But since the question says you should determine the sum of the 2 fractions, therefore you should multiply \frac{17}{15} by 7. Therefore you should have:

\frac{17}{15} X 7 (7 can also be expressed as \frac{7}{1})

= \frac{17}{15} x \frac{7}{1} (notably, in multiplication there is no need for the fraction to have the same denominator. You can multiply both numbers at the top together (numerator) and do same with the denominator.

= \frac{119}{15}

= 7\frac{14}{15}

Therefore, 7 times as much as the sum of \frac{1}{3} and \frac{4}{5} is 7\frac{14}{15}

<h3>What is interest?</h3>

The amount of money a lender or financial organization earns for lending out money is known as interest.

We know that monthly payments include the interest on the principal amount that is not been paid during the purchase of an item, if the down payment is more than the principal amount that the customer does not pay will decrease which will decrease the loan amount, thus, the interest on the principal amount will decrease as well.

Now, as the interest and the principal amount have both is been reduced, therefore, the monthly instalment(monthly payment) will be reduced as well.

Hence, the correct option is D, A bigger down payment is money paid toward principal, interest-free, which also decreases the amount paid monthly.
