Answer 1

Answer:

1/4

The Clock Shows 12 hours so it is Divided Equally into 12 Parts.

Now the Hour Hand Covers 3 Horurs When it Moves From "7" to "10".

So, it Covers 3 Parts Out of 12 as Mentioned above.  

Now The Fraction is :-   The Part it Covered / Total No of Parts

                                   =    i.e 3/12

                                   =    1/4  ( Which is Simplified Form of 3/12)

Therefore Hour Hand Covers 1/4 part of Clock when it Moves From 7 to 10
