You have to show how they do not have a ratio equal to eachother. So, as an example, the first euro is smaller, but you have to see it's ratio. But the thing about the smaller euro, you cannot simplify it, so it is technically impossible to do this. I am not sure if this is the way to do this, as Its 4:37 and I woke up due to a large clap of thunder and im really tired. But hopefully this helps.
Have a great day!
