The answer depends on the units for 50.
1km = 1000m20m/1km:= 20m/1000m= 2/100 or 1/50
As a fraction it is 50/1000 or 1/20 in its simplest form
1km = 1000m520m/1km:= 520/1000 or 13/25 of 1km
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
If you mean 700cm then it is 7/10 of 1km
fraction: 77/10001 km = 1000 m77m/1km = 77m/1000m = 77/1000
Make the units the same, in this case m. 1 km = 1000 m So 50/1000 = 1/20
1km = 1000m ⇒ 700m out of 1km = 700/1000 = 7/10
100000cm = 1km 50cm = 1km/1000000cm/1km 0.00005km = 50cm 50cm < 1km
fraction = 253m/1000m = 253/1000
3/4.
1/40 is the answer
