Answer 1

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?

The 1,609 meters and the 804.5 meters in Step 1 should be switched.
The 1 mile and 804.5 meters in Step 1 should be switched.
The conversion factor should be added in Step 2 instead of being multiplied.
The conversion factor should be divided in Step 2 instead of being multiplied.
