If the istance Anya ran was 1/5 of the length of the track, what fraction would you use to represent the whole track?

5/5

Step-by-step explanation:

According to the statement Anya ran 1/5 of the track, the fraction of the entire track would be unity. To represent unity in this case we would have to add 5 times the distance Anya traveled, since she traveled the fifth part, that is:

1/5 + 1/5 + 1/5 + 1/5 + 1/5 = 5/5

In this case the unit and fraction representing the entire track is 5/5
