I believe this is the question: "Quadrilateral ABCD in the figure below represents a scaled-down model of a walkway around a historic site. Quadrilateral EFGH represents the actual walkway. ABCD is similar to EFGH. Two irregular similar quadrilaterals ABCD and EFGH are drawn. AB measures 5 inches, BC measures 4 inches, CD measures 4 inches and AD measures 3 inches. EF measures 45 feet. What is the total length, in feet, of the actual walkway?"
We should determine the ratio(proportionality) of the two similar quadrilaterals. Since AB corresponds to EF, AB=5, EF=45, we know that the side lengths of EFGH is 45/5=9 times those of ABCD. The perimeter of ABCD=5+4+4+3=16 feet, so the perimeter of EFGH, the actual pathway, is 16*9=144 feet.
Probabilities! In order to find the answer you first have find out the total amount of marbles that you have. So:
[7 + 9 + 6] = 22
This number will go into the denominator.
The next step is to find how how many marbles are not green. To do that you simply add the red marbles and the blue marbles. So:
[7 + 9] = 16
This number will go in the numerator.
The probability of you choosing a marble that is not green is 16/22. You can also simply this and it would be 8/11.
I hope this helps you

2, 4, 8, 12 are all common denominators because they can become the same denominator
Decimal: .32
fraction: 32/100 which, when reduced, is 8/25
