How does it work?

The principle behind finding a fraction of a number, such as 1/9 of 22, is rooted in the method of cross-multiplication.

Consider the following proportion: 1 9 = x 22 (where x represents 1/9 of 22)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 1 × 22 = 9 x
  2. Which gives: 22 = 9 x
  3. Divide both sides by 9 to isolate x: 22 9 = 9 x 9
  4. Which gives the result: 22 9 = x

Thus, 1/9 of 22 is equal to 22/9 (or 2.4444444444444 in its decimal form).
