draw some quadrilaterals. one fifth is blue. one half is yellow.

assistance needed
School subject is Math, not 5th grade. 
Ok. so you take the area of the quadrilateral. Let's say it was 16(4x4). You divide 16 by 5 and you should get 16 or 3 1
 
5 5
So you want to color 3 whole squares and 1/5 of one. Divide one square into fifths.
The onehalf should be easy. Just shade in half of your shape.
I don't know if I did that right so you might want to check with someone else but see if it works.
