Solve the proportion:
4/x = (radical sign over 11, not 1) 11  1/3
Please solve and explain. My answer does not match any of my choices.

bobpursley,
4/x= sqrt11 1/3
x= 4/(sqrt111/3)
Now some would rationalize the denominator, but multiplying the right side by sqrt11+1/3
x=4(sqrt11+1/3)/(111/9)

bobpursley,
are you certain you copied this correctly? This is a little complicated for an Algebra I student.

Jane,
It is copied correctly. My choices are:
6/5 sqrt11 + 6/5
5/6 sqrt11 + 6/5
6/5 sqrt11  6/5
5/6 sqrt11  6/5
