Answer 1

Rectángulo entero: 20/20

A :

(2 + 2(2×1)/2 + 2(1×1)/2)/20 =

(2 + 2 + 1)/20 =

5/20 = 1/4

B:

((4×2)/2)/20 =

4/20 = 1/5

C:

((2×1)/2 + 2×(1×1)/2)/20 =

(1 + 1)/20 =

2/20 = 1/10

D:

(4 + 2×(2×1)/2)/20 =

(4 + 2)/20 =

6/20 = 3/10

E:

(2 + (2×1)/2)/20 =

(2 + 1)/20 = 3/20

A + B + C + D + E =

1/4 + 1/5 + 1/10 + 3/10 + 3/20 = 1
