In the Educación Secundaria Matemáticas book, there is a problem about the price of a bag of oranges. I found the same problem here on page 4, except that it´s a box of oranges.
How would you read aloud 4,8 '? "cuatro y ocho décimo euros"? "cuatro coma ocho euros"?
If memory serves correctly, on Mi Vida Loca they said, for example, "cuatro con cincuenta" for 4 Euros and 50 cents.
Is this just written this way because it's in a math problem? Do signs in stores actually say 4,8 ? (rather than 4,80 ')?
