Interrogative adjectives may be preceded by a preposition:
- ¿A qué hora es la clase? (At what time is the class?)
- ¿De cuántas personas estamos hablando? (How many people are we talking about?)
- ¿Con cuánto dinero viajarás? (How much money you will travel with?

Exclamatory adjectives have the same form as the interrogative adjectives, and we use them to add intensity to exclamations:
- ¡Qué día mas hermoso! (What a (most) beautiful day!
- ¡Mira qué mirada que tiene esa chica! (Look at (how intense) her stare!
- ¡Cuánta pobreza hay en el mundo! (How much poverty there is in the world.)
