How does it work?

The principle behind finding a fraction of a number, such as 1/10 of 79, is rooted in the method of cross-multiplication.

Consider the following proportion: 1 10 = x 79 (where x represents 1/10 of 79)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 1 × 79 = 10 x
  2. Which gives: 79 = 10 x
  3. Divide both sides by 10 to isolate x: 79 10 = 10 x 10
  4. Which gives the result: 79 10 = x

Thus, 1/10 of 79 is equal to 79/10 (or 7.9 in its decimal form).
