Consider the following proportion: 8 9 = x 92 (where x represents 8/9 of 92)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 8 × 92 = 9 x
  2. Which gives: 736 = 9 x
  3. Divide both sides by 9 to isolate x: 736 9 = 9 x 9
  4. Which gives the result: 736 9 = x

Thus, 8/9 of 92 is equal to 736/9 (or 81.777777777778 in its decimal form).
