The fraction of the hour joey used for practicing the piano can be gotten from the gaps in the number line.
Since there are 3 equal gaps in the number line , this denotes the fraction of the hour that each gap would represent is
[tex]\frac{1}{3}[/tex]
This implies that the first point is = 0

This implies that the third point is = 2/3
This implies that the fourth point is = 1
In conclusion, the answer is B for the second point.
