To find the unit rate of euros per dollar, we divide the amount of euros by the amount of dollars:
[
text{Unit Rate} = frac{text{Euros}}{text{Dollars}} = frac{450 text{ euros}}{600 text{ dollars}}.
]
Now, simplify this fraction:
[
frac{450}{600} = frac{450 div 150}{600 div 150} = frac{3}{4} = 0.75.
]
So, the unit rate is 0.75 euros per dollar.
