How does it work?

The principle behind finding a fraction of a number, such as 5/8 of 35, is rooted in the method of cross-multiplication.

Consider the following proportion: 5 8 = x 35 (where x represents 5/8 of 35)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 5 × 35 = 8 x
  2. Which gives: 175 = 8 x
  3. Divide both sides by 8 to isolate x: 175 8 = 8 x 8
  4. Which gives the result: 175 8 = x

Thus, 5/8 of 35 is equal to 175/8 (or 21.875 in its decimal form).
