Look 6 small rectangles are there. The shaded part is - (half+half)+(half+half)+half small rectangles =(1+1)+half small rectangles=2+half small rectangles=2 and half small rectangles.You want to shade 2 more small rectangles.Then the shaded part will be=2 and half +2 small rectangles= 4 and half small rectangles. Then the unshaded part will be =6 - 4 and half small rectangles=1 and half small rectangles.The fraction of unshaded small rectangles will be =1 and half by 6=3 by 12=2 by 8=1 by 4. So the answer will be (a) 1 by 4

1. First Row's Shaded Portion = 1 Square. 2. 2nd Row's 1st Square's 2nd Square's shaded portion = 1.5 Square. 3. 3rd Row's 1st Square's 2nd Square's shaded portion = 1 Square 4. 2nd Row's 3rd Square 3rd Row's 3rd Square's shaded portion = 1 Square So total 4.5 Square are there which is 1/2 of total 9 Square Hence, the Answer is : 1/2.

Ans 2:
