    So are you trying to find what d is if sixteen and two thirds percent of d is 4?

    Get rid of the percentage and re-write the equation using fractions:

    16 \frac23 \% \cdot d =  \frac{50}3 \% \cdot d = \frac{50}3 \cdot \frac1{100} \cdot d  = \frac{50}{300} \cdot d = \frac16 d

    So your equation becomes:

    \frac16 d = 4

    Solve for d.
