How does it work?

The principle behind finding a fraction of a number, such as 7/8 of 93, is rooted in the method of cross-multiplication.

Consider the following proportion: 7 8 = x 93 (where x represents 7/8 of 93)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 7 × 93 = 8 x
  2. Which gives: 651 = 8 x
  3. Divide both sides by 8 to isolate x: 651 8 = 8 x 8
  4. Which gives the result: 651 8 = x

Thus, 7/8 of 93 is equal to 651/8 (or 81.375 in its decimal form).
