The following shows the process a student used to determine the number of yards in 3,218 meters.
(1 mile = 1,609 meters) (1 mile = 1,760 yards)
Step 1: 1,609 meters is being multiplied by conversion factor 1 mile over 3,218 meters equals 0.5 mile
Step 2: 0.5 mile is being multiplied by conversion factor 1760 yards over 1 mile equals 880 yards
Step 3: 880 yards
Step 1 is incorrect as the ratio should be set up as
3,218 meters is being multiplied by conversion factor 1 mile over 1,609 meters equals 2 miles
which follows to give an ans of 3,520 yards
