Since 99/4 is an improper fraction, the result could also be expressed as a mixed number: 24 3/4

How does it work?

The principle behind finding a fraction of a number, such as 3/4 of 33, is rooted in the method of cross-multiplication.

Consider the following proportion: 3 4 = x 33 (where x represents 3/4 of 33)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 3 × 33 = 4 x
  2. Which gives: 99 = 4 x
  3. Divide both sides by 4 to isolate x: 99 4 = 4 x 4
  4. Which gives the result: 99 4 = x

Thus, 3/4 of 33 is equal to 99/4 (or 24.75 in its decimal form).
