1.) top row: 100 200 300 400 500 600. Bottom row: 5 10 15 20 25 30
2. Each ratio is just the top row divided by the bottom row. So the second thing in the ratio would be 200/10, the third one 300/15, etc. Each ratio is equal to 20.
3.) if x is gallons of gas used, y is distance driven. the equation that describes this relationship is y=20x.

The initial measure is:
m1 = 28 ft
The real measure must be:
m2 = 14 ft
The correct procedure to determine the scale factor is:
$k = m1 / m2

k = 28/14$
Dividing both numbers between 14 we have:
$k = (28/14) / (14/14)$
Rewriting:
$k = 2/1

k = 2$
Answer:
Zelie should have divided both numbers by 14.
