lan completed part of a race and had 2000m
left to run.if he had completed 3/5 of the race,what is the total distance he had to run?
Let the total distance be x m
since he completed 3/5 of the race, he still has 2/5 of the race to run, but this is supposed to be 2000 m
then (2/5)x = 2000
multiply both sides by 5/2,
typo in second-last line
should be: (5/2)*(2/5)x = 5/2*2000
