Answer:
Sara's total distance is 4/7 around the track
Explanation:
To complete this problem, just multiply how much of Jason's distance Sara ran, 4/5, by Jason's distance around the school track, 5/7:
4/5 x 5/7 = 20/35
Now simplify the product (The greatest common factor of 20 and 35 is 5):
20/35 = 4/7 total distance
