Discuss and learn French: French vocabulary, French grammar, French culture etc.
1.5 Euros = un euro et demi
0.75 euro = soixante-quinze eurocents.
I have heard "un euro vingt-cinq" on the streets of Paris. Or "due euros trente", etc. And if no cents are called for, the word "euro(s)" is even eliminated from amounts answered when euros are implied:
"Combien pour cela?
"Eurocents" isn't used, we still say "centimes", but Charles is right as well we tend to drop the "centimes" (or the "euro") anyway (exept when the amount has no full euro in it).
So to me:
1,5€ = "un euro cinquante" or even "un cinquante" but some still say "un euro et cinquante centimes", I've heard all three (the first one being the most common).
0,75€= "soixante-quinze centimes"
