Consider the following proportion: 4 7 = x 73 (where x represents 4/7 of 73)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 4 × 73 = 7 x
  2. Which gives: 292 = 7 x
  3. Divide both sides by 7 to isolate x: 292 7 = 7 x 7
  4. Which gives the result: 292 7 = x

Thus, 4/7 of 73 is equal to 292/7 (or 41.714285714286 in its decimal form).
