How does it work?

The principle behind finding a fraction of a number, such as 1/10 of 49, is rooted in the method of cross-multiplication.

Consider the following proportion: 1 10 = x 49 (where x represents 1/10 of 49)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 1 × 49 = 10 x
  2. Which gives: 49 = 10 x
  3. Divide both sides by 10 to isolate x: 49 10 = 10 x 10
  4. Which gives the result: 49 10 = x

Thus, 1/10 of 49 is equal to 49/10 (or 4.9 in its decimal form).
