प्रश्न
What fraction of a clockwise revolution does the hour hand of a clock turn though, when it goes from 4 to 7?
उत्तर
We may observe that in 1 complete clockwise revolution, the hour hand will rotate by 360°.
When the hour hand goes from 4 to 7 clockwise, it will rotate by 1 right angle or 90º.
Fraction = `90^circ/360^circ = 1/4`
