First change it to a mixed number is between 2 and 3, closer to 3.
Draw a number line:
This would be 2 plotted on a number line:
-------------------------------------⚫------------------
-4 -3 -2 -1 0 1 2 3 4 5
This would be 3 plotted on a number line:
-------------------------------------------⚫------------
-4 -3 -2 -1 0 1 2 3 4 5
So to plot you would estimate about ths
of the distance from 2 toward 3, like this, and put the
mark there:
-----------------------------------------⚫--------------
-4 -3 -2 -1 0 1 2 3 4 5
