प्रश्न
What fraction of a clockwise revolution does the hour hand of a clock turn though, when it goes from 6 to 3?
उत्तर
We may observe that in 1 complete clockwise revolution, the hour hand will rotate by 360°.
When the hour hand goes from 6 to 3 clockwise, it will rotate by 3 right angles or 270º.
Fraction = `270^circ/360^circ = 3/4`
