= 8 hours + 1/2 x 60 mins (.: 1 hour = 60 mins, Therefore, 1/2 hours = 30 mins)
= 8 hrs 30 min.
Therefore, we can write 8-hrs 30-min as 17/2.
While solving problems, make all numbers in vulgar fraction, it will be easy to solve problems quickly.
For example: 360/12 x 17/2 = ?
It is easy to solve. Have a nice day!

Try this formula it can solve any tipe of clock related problem.
Angle b/w two handes of the clock= (11/2) *min-30*hr;.

8hr+30/60=17/2.

It is . . . . Very simple
by the Formula:
30H-[11/2]M
at 8.30
i.e 240-165=75degrees
I hope that every one understood this . . . . .

We can use other formula too...
30h-6m
where:
H=total hours including minute parts...
m=minutes
in above qn it would be
30*17/2-6*30=255-180=75;
Hope its easier formula.

Hours hand should be calculated by considering
hours Hand -( 8 * 360/12)= 240 deg
Minutes Hand - ( 30 * 360/60) = 180 deg
Total angle b/w Hour and Min = 240 -180 = 60 deg.
This is Practically as per the clock system.

Can we write 17/2 we also write this 34/4 that is also equals.

Hey guys...
no need to apply any formula..
just look at any clock,each division(1/12) is 360/12=30 deg,and 1/24 division is 15 deg,so in 8:30--> 30+30+15=75 deg
Required angle = (255 - 180)º = 75º.
