Question

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

Answer 1

Wow... tough to read and understand

here is what I would do

3218/1609 =        this will tell you how many miles are in 3218 metres

next take your answer and then multiply it by 1760 to tell you how many yards are in 3218 metres

Answer 2

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
