Because the 'normal' way to count is upwards.
On a clock face a quarter to 12 is equal to 11:45am or 11:45pm
No. 12:00am
11:45
10:01, 12:21, 11:11
It means from 12 a clock to 11:59 in the morning.
11:45
12 hour clock's have am and pm. 24 hour clock's (military time) is 00:00 through 23:59. Midnight on a 12 hour clock is 12:00am, on a 24 hour clock is 00:00. So 23:59 would be 11:59pm.
11
5 + 11 is 16 take away 12 leaving 4
using mod 12 arithmetic, 11x3 = 9 mod 12
10:10, 11:11, 12:12 = 3/12 = 1/4 = 25% of the time.
11 o clock or 12
