When speaking Spanish, it is important to know how to express the concept of “100%.” However, non-native speakers often make mistakes when using this word. In this section, we will introduce some common errors and provide tips to avoid them.

Common Mistakes

  • Using “cien” instead of “ciento”: “Cien” means “one hundred,” while “ciento” means “one hundred percent.”
