How does it work?

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

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

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 9 × 92 = 5 x
  2. Which gives: 828 = 5 x
  3. Divide both sides by 5 to isolate x: 828 5 = 5 x 5
  4. Which gives the result: 828 5 = x

Thus, 9/5 of 92 is equal to 828/5 (or 165.6 in its decimal form).
