You can do this !
Since d=3, take your pencil and write the fraction again,
except wherever 'd' appears, write a '3' there instead.
Then you'll have a fraction with nothing but numbers in it, and
you can easily simplify and find the value of the fraction.
I did it in my head as I was looking over the picture, and
I found that the value of the fraction is between 5 and 10.
I don't want to just hand you the answer, because I know
that you can do it.
