Help meh please I don’t get it

Answer 1

Figure out how much Kuna you have left, and multiply that number by .17

Answer 2

How much of the Croatian currency you have left is irrelevant. 

Instead, begin with $1000

and mult. that by the conversion rate:

$1000      5.81 Kuna
--------- * ------------------ 5810 Kuna (answer)
     1            $1.00
