How does it work?

The principle behind finding a fraction of a number, such as 4/3 of 38, is rooted in the method of cross-multiplication.

Consider the following proportion: 4 3 = x 38 (where x represents 4/3 of 38)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 4 × 38 = 3 x
  2. Which gives: 152 = 3 x
  3. Divide both sides by 3 to isolate x: 152 3 = 3 x 3
  4. Which gives the result: 152 3 = x

Thus, 4/3 of 38 is equal to 152/3 (or 50.666666666667 in its decimal form).
