Translation by Mimiwhatsup:
Elsa: Good afternoon, Laura. What time is the French class? Laura: It's at ten minus twenty-five. Elsa: Thank you, what about the chemistry class? Laura: It starts at twelve and a quarter.
3rd Option 9:35 and 12:15
As it starts Ten minus 25. There is 60 minutes in an hour we already know it must start at the hour 9 so 60 - 25 = 35. So it's at 9:35. The Chemistry class hour we know too it's 12 and a quarter is 15.
