400/1000 = 2/5
100/1000 = 1/10
If you mean 700cm then it is 7/10 of 1km
3/4
There is 1000m in 1km, therefore the fraction is 1000/50 which can be simplified to 100/5 which can be simplified to 20/1. So 50m is one 20th of 1km. So you need to run 20 times further to make the 1k fatty! lol
400/1000 = 2/5
1/40 is the answer
1km = 1000m ⇒ 700m out of 1km = 700/1000 = 7/10
1/10
100/1000 = 1/10
1km = 1000m520m/1km:= 520/1000 or 13/25 of 1km
If you mean 700cm then it is 7/10 of 1km
fraction: 77/10001 km = 1000 m77m/1km = 77m/1000m = 77/1000
1km = 1000m20m/1km:= 20m/1000m= 2/100 or 1/50
fraction = 253m/1000m = 253/1000
3/4.
