We may observe that in 1 complete clockwise revolution, the hour hand will
rotate by 360º.
(a) When the hour hand goes from 3 to 9 clockwise, it will rotate by 2 right angles or 180º.
Fraction = 
(b) When the hour handgoes from 4 to 7 clockwise, it will rotate by 1 right angle or 90º.
Fraction= 
(c) When the hour handgoes from 7 to 10 clockwise, it will rotate by 1 right angle or 90º.
Fraction= (d) When the hour handgoes from 12 to 9 clockwise, it will rotate by 3 right angles or 270º.
Fraction=
(e) When the hour handgoes from 1 to 10 clockwise, it will rotate by 3 right angles or 270º.
Fraction= (f) When the hour handgoes from 6 to 3 clockwise, it will rotate by 3 right angles or 270º.
Fraction=
