i need help on a story problem? Jason ran 5/7 of the distance around the school track. Sara ran 4/5 of Jason's distance. What fraction of the total distance around the track did Sara run?
The first thing you do is to find the lowest common multiple of 5 and 7.What you do on the bottom, you must do on the top 25/35 / 28/35. The answer is 25/28. Sara ran 25/28 of the total distance around the track.
