Who ran the farthest and by how much?

Question

 Sophia Kaitlyn and Morgan  wanted to see how far they could run in five minutes. Sophia ran 1/2 of a mile, Kaitlyn ran 9/10 of a mile, and Morgan ran 2/3 of a mile.

Answer 1

Kaitlyn ran farthest with 9/10 of a mile = 0.9 miles = 27/30 mile

Morgan ran next with 2/3 of a mile = 0.666... miles = 20/30 mile

Sophia ran last with 1/2 a mile = 0.5 miles = 15/30 mile

Kaitlyn ran 7/30 of a mile more than Morgan, and she ran 13/30 of a mile more than Sophia
