Answer:
12:45 pm and 7:30 pm
Explanation:
In a 24 hour clock, we don't use pm or am to identify time. But in a 12 hour clock , am or pm is used. Given time is in 24 hour clock.
So, for 12:45, in 12 hour clock it will be 12:45 pm because, when the time crosses 11:59, it becomes pm.
For, 19:30, it will 19:30-12:00= 7:30 pm.
