What is 2/2 of 19?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 2/2 of 19? We'll show you a straightforward method to achieve that.

How to calculate 2/2 of 19?

  1. Multiply the whole number by the numerator of the fraction: 19 × 2 = 38
  2. Divide this result by denominator of the fraction: 38/2 = 19
  3. Simplify by dividing both the numerator and denominator by their GCD (2):
    • 38/2 = 19
    • 2/2 = 1
  4. Which gives: 19/1

How does it work?

The principle behind finding a fraction of a number, such as 2/2 of 19, is rooted in the method of cross-multiplication.

Consider the following proportion: 2 2 = x 19 (where x represents 2/2 of 19)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 2 × 19 = 2 x
  2. Which gives: 38 = 2 x
  3. Divide both sides by 2 to isolate x: 38 2 = 2 x 2
  4. Which gives the result: 38 2 = x (or 19 1 = x )

Thus, 2/2 of 19 is equal to 19/1 (or 19 in its decimal form).
