Question
What is the disadvantage in comparing line segments by mere observation?
✓
Answer
By looking at the clock we can see when the hour hand goes from $12$ to $9$ it basically covers three right angles which is of $= 90 + 90 + 90 = 270^\circ .$
Therefore, required Fraction = $\frac{270}{260}$ = $\frac{3}{4}$
Therefore, required Fraction = $\frac{270}{260}$ = $\frac{3}{4}$
