The first thing you'd need to do is convert the 1 kilometer to meters. 1 kilometer = 1,000 meters So, the fraction would start as 45 over 1,000, but that fraction can be simplified. Both numbers can be divided by 5. 45 divided by 5 = 9 1,000 divided by 5 = 200 The final fraction would be 9 over 200 or 9/200.
