Answer:
increase, 100%.

2/3 is 1/3 + 1/3. if you think of 1/3 as your starting point, you want to know how much you have changed, but IN TERMS OF 1/3. one way to do this is to subtract your starting value (1/3) from your new value, and then divide.
[tex]\frac{2}{3}-\frac{1}{3} = \frac{1}{3} \\\\[/tex]
[tex]\frac{1}{3}[/tex]÷[tex]\frac{1}{3}[/tex]
which is really
[tex]\frac{1}{3}[/tex]×[tex]\frac{3}{1}[/tex]
which simplifies to 1.
