How does it work?

The principle behind finding a fraction of a number, such as 5/9 of 92, is rooted in the method of cross-multiplication.

Consider the following proportion: 5 9 = x 92 (where x represents 5/9 of 92)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 5 × 92 = 9 x
  2. Which gives: 460 = 9 x
  3. Divide both sides by 9 to isolate x: 460 9 = 9 x 9
  4. Which gives the result: 460 9 = x

Thus, 5/9 of 92 is equal to 460/9 (or 51.111111111111 in its decimal form).
