How does it work?

The principle behind finding a fraction of a number, such as 10/3 of 65, is rooted in the method of cross-multiplication.

Consider the following proportion: 10 3 = x 65 (where x represents 10/3 of 65)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 10 × 65 = 3 x
  2. Which gives: 650 = 3 x
  3. Divide both sides by 3 to isolate x: 650 3 = 3 x 3
  4. Which gives the result: 650 3 = x

Thus, 10/3 of 65 is equal to 650/3 (or 216.66666666667 in its decimal form).
