Here is a clock.
The long blue hand is pointing to the 3, which is a quarter way round, so the time will be something 15 or a quarter past.
The short red hand is pointing to between the 5 and the 6, so the time is:
5:15
or a quarter past 5.
Here is another clock.
The long blue hand is pointing to the 9, which is three-quarters the way round, so the time will be something 45 or a quarter to the next hour.
The short red hand is pointing to between the 3 and the 4, so the time is:
3:45
or a quarter to 4.
