You can put this solution on YOUR website! The minute hand of a clock points directly at the 11. What number will the minute hand point at after 5,555 minutes?
The minute hand takes 5 minutes to point to the next number, so
we divide
1111
5)5555
So it has pointed to a new number exactly 1111 times in those 5555 minutes.
Now every time it has pointed to 12 new numbers it has made a complete
revolution. So we divide again, this time by 12:
92
12)1111
108
31
24
7
So it has made 92 complete revolutions and ended up with
a remainder of 7 more numbers than those 92 complete
revolutions from where it started, and so it has ended up 7
numbers past pointing to the 11, and that makes it point to the
number 6.
