The steps below show the work of a student used to calculate the number of yards in 6,436 meters.
(1 mile = 1,609 meters)
(1 mile = 1,760 yards)
step 1: 6,436 meters multiplied by conversion factor 1 mile over 1,609 meters equals 4 miles
step 2: conversion factor of 1,760 yards over 1 mile divided by 4 miles equals 440 yards
step 3: 440 yards
(1 mile = 1,609 meters)
(1 mile = 1,760 yards)
how can the error in the student's work be corrected?
a. the 6,436 meters and the 1,609 meters in step 1 should be switched.
b. the 1 mile and the 1,609 meters in step 1 should be switched.
c. the conversion factor should be multiplied in step 2 instead of being divided.
d. the conversion factor should be added in step 2 instead of being divided.
