Witch list shows the fractions in order from least to greatest?

a. 2/3,3/4,7/12?
b. 7/12,3/4,2/3?
c. 3/4,2/3,7/12?
d.7/12,2/3,3/4?

2/3 = 8/12

3/4 = 9/12

7/12 = 7/12

So the ordert form is

7/12 ; 2/3 ; 3/4

Answer D is correct.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
