Verified Answer :

1 kilometer = 1000 meter
Then
4.5 kilometers = (1000/1) 4.5 meters
                        = 1000
4.5 meters
                         = 1000 (45/10) meters
                         = 100
45 meters
                         = 4500 meters
So there are 4500 meters in 4.5 kilometers

We already know that
1 feet = 12 inches
Then
5 feet = (12/1) 5 inches
           = 12
5 inches
           = 60 inches
So there are 60 inches in 5 feet.
I hope the procedure of conversion is clear to you.

1 Kilometer = 1000 meters
4.5 kilometers = 4500
With this you would multiply 4.5 by 1000.
12 inches = 1 foot
 60 inches = 5 feet
With this you would multiply 5 by 12.
Hope this helps! :)
