I got D.

Not sure if I should post my explanation.

Mark, further clarification would be great. Should I post my explanation right away or wait a specific amount of time before editing my post ?

Edit:Explaining my method

I simply converted everything to decimals and simplified.
I got 3.125 in the numerator and .625 in the denominator.

Hi Mr Mark Dabral,
It took me 10s to do it, (answer is D)
iI just multiplied the numerator and the denominator by 2^3
and got the amount equivalent to ( 2^3 + 2^4 + 1)/( 1 + 2^2) which equals to ( 8+16+1)/(1=4) = 25/5 = 5

I hope I am right
