How does it work?

The principle behind finding a fraction of a number, such as 1/4 of 23, is rooted in the method of cross-multiplication.

Consider the following proportion: 1 4 = x 23 (where x represents 1/4 of 23)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 1 × 23 = 4 x
  2. Which gives: 23 = 4 x
  3. Divide both sides by 4 to isolate x: 23 4 = 4 x 4
  4. Which gives the result: 23 4 = x

Thus, 1/4 of 23 is equal to 23/4 (or 5.75 in its decimal form).
