There are 5,280 feet in a mile. if ann ran 1,320 feet and walked 3,960 feet, her total distance would be one mile. what fraction of the mile did she run? what fraction of the mile did she walk?

To figure out the answer to this problem, you need to divide the amount of feet Ann ran by the amount of total feet that Ann covered. 

1320/5280 is your fraction.

If you simplify this fraction, you get 1/4, which is 0.25 or 25% of the mile.

127 millimeters is the answer
