Time in French is a bit weird, since there is a fractions rule regarding time. When it is 15 minutes into the hour, such as 1:15, you’d say “une heure et quart” (One hour and a quarter). When it is 30 minutes into the hour, such as 3:30, you’d say “trois heures et demie” (Three hours and a half). At 45 minutes into the hour, you’d say “Moins le quart” (Minus a quarter). However, this way of speaking is informal and only used through hours 1-12. Since we’re on a 24-hour clock, you’d use the formal “Dix-huit heures le quarante-cinq”. However, the choices are 17h45, 5h45, 6h45, and 19h15. None of the answers are correct.
