Since 333/5 is an improper fraction, the result could also be expressed as a mixed number: 66 3/5

How does it work?

The principle behind finding a fraction of a number, such as 9/5 of 37, is rooted in the method of cross-multiplication.

Consider the following proportion: 9 5 = x 37 (where x represents 9/5 of 37)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 9 × 37 = 5 x
  2. Which gives: 333 = 5 x
  3. Divide both sides by 5 to isolate x: 333 5 = 5 x 5
  4. Which gives the result: 333 5 = x

Thus, 9/5 of 37 is equal to 333/5 (or 66.6 in its decimal form).
