Answer:

This is incorrect because when you seperate both equations, the 7/x flips to x/7. x times x does not cancel out, and the correct division gives you x²/21

Step-by-step explanation:

(x/3)/(7/x)

(x/3) ÷ (7/x)

(x/3) × x/7

x²/21

Answer:

(x^2) / 21

Step-by-step explanation:

To divide a quantity by a fraction, invert the fraction and then multiply.  Cancelling the "x" in the given problem does not accomplish this.

(x/3) divided by (7/x) is equivalent to (x/3) times (x/7), or x^2 / 21.
