Answer: 3 & 6/11 (choice B)
===========================================
Work Shown:
39/11 = (33 + 6)/11
39/11 = (33/11) + (6/11)
39/11 = 3 + (6/11)
39/11 = 3 & 6/11
------------
Or you could use a calculator to see that
39/11 = 3.545 approximately
The whole part is 3 which is the stuff to the left of the decimal point.
The remainder is 39-3*11 = 39-33 = 6 which is the numerator of the fractional part. Therefore the improper fraction 39/11 converts to the mixed number 3 & 6/11.
