The easiest way to do this is to split each figure into smaller shapes.
1. a rectangle and a triangle
2. 3 separate rectangles
3. triangle and rectangle
... so on
You then find the areas of the smaller shapes and then add them together.
1. (for rectangle) 6*3 = 18
(for triangle) (12*15)/2 = 90 90 + 18 = 108
2. 4*8 = 32
8*4 = 32
12*12 = 144 32 + 32 + 144 = 208
...so on

3* ( 1/3 -5)= -14 hope this helps
You have to give them the same denominator so multiply 11/12 by 4 and 3/16 by 3. giving you 44/48 and 9/48. then divied 44 by 9 giving you 4.8888
there for there are 4 whole 3/16 sections of the 11/12 board
