Xian plans to run 20 laps around a track. Each lap is 400 yards. So far Xian has to run 1680 yards around the track. What percentage of the run has Xian completed.
First convert laps to yards. 20 * 400 = 8000 yards. This is the total amount of yards that Xian plans to run. He has already completed 1680 of the 8000, so divide 1680/8000 and get .21, then multiply by 100 to get your percent. 21%
