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 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
