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

first row shaded areamakes one square. last row first n second shaded area makes second square. third column last two shaded area makes third square. middle square is fourth shaded square. first column middle square is half shaded square. thus totoal shaded squares are 4.5 and divided by total number of squares, i.e. 9 equals 4.5/9=1/2

Ans 3:

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.
