You can put this solution on YOUR website! Represent the numbers 36/9 and 2/5 on a number line.
---------------------
36/9 = 4
---
2/5 = 0.4
------------------------
Draw a number line.
Put unit marks from -3 on the left of zero to +5 on the right.
Put a solid circle at "4".
Pt a solid circle 2/5 th of the way from 0 to 1.
Don't be picky; just put a solid circle and call the
point 0.4.
