Question

What fraction of a clockwise revolution does the hour hand of a clock turn though, when it goes from 7 to 10?

Answer 1

We may observe that in 1 complete clockwise revolution, the hour hand will rotate by 360°.

When the hour hand goes from 7 to 10 clockwise, it will rotate by 1 right angle or 90º.

Fraction = `90^circ/360^circ = 1/4`
