Question

On a trip, you had to change your money from dollars to euros. You got 450 euros for 600 dollars. Which is a unit rate that describes the exchange? A.0.75 euros per dollar B.4.5 euros per dollar C.6 euros per dollar or D.6 euros per dollar

Answer 1

The number of Euros received against 600 dollars = 450
Then
For 1 dollar, the number of euros = (450/600) euros
                                                       = (45/60) euros
                                                       = ( 3/4) euros
                                                       = 0.75 euros
So the unit rate that describes the exchange rate is 0.75 euros per dollar. So the correct option among all the options given in the question is option "A". I hope the procedure for getting to the correct result is clear enough for you to understand. In future you can use this procedure for solving similar problems.
