While vacationing,john has dinner at a restaurant in Japan and his tab
comes to 3,428 yen. The exchange rate at the time of his visit is 1 yen = 1.25
cents. What was the cost of the meal in US dollars??

1 yen = 1.25 cents.
100 yens = 125 cents = 1.25$
So 3428 yens = 3428/1.25 $ 
Is this the final answer? Or do i need to divide 3428 by 1.25$ to get the final answer?

$3428/1.25 is the same as
$3428÷1.25
Yes, you will have to take the calculator and do the division to get the final answer.
Feel free to post the final answer for verification if you wish. 
I came up with $ 2,742.4

I apologize that I was completely off.
Let's start over.
1 yen equals 1.25 cents = $0.0125
so by direct proportion:
1 yen : $0.0125
3428 yens : $X
so by cross multiplication:
$X = $0.0125*3428yens/1 yen
= $42.85
