Consider the following proportion: 8 9 = x 38 (where x represents 8/9 of 38)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 8 × 38 = 9 x
  2. Which gives: 304 = 9 x
  3. Divide both sides by 9 to isolate x: 304 9 = 9 x 9
  4. Which gives the result: 304 9 = x

Thus, 8/9 of 38 is equal to 304/9 (or 33.777777777778 in its decimal form).
