The steps below show the work of a student used to calculate the number of yards in 804.5 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 804.5 meters equals 2 miles

step 2: 2 miles is being multiplied by conversion factor 1760 yards over 1 mile equals 3,520 yards

step 3: 3,520 yards
(1 mile = 1,609 meters)
(1 mile = 1,760 yards)

how can the error in the student's work be corrected?
