What is 2/1 of 68?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 2/1 of 68? We'll show you a straightforward method to achieve that.

How to calculate 2/1 of 68?

  1. Multiply the whole number by the numerator of the fraction: 68 × 2 = 136
  2. Divide this result by denominator of the fraction: 136/1 = 136

How does it work?

The principle behind finding a fraction of a number, such as 2/1 of 68, is rooted in the method of cross-multiplication.

Consider the following proportion: 2 1 = x 68 (where x represents 2/1 of 68)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 2 × 68 = 1 x
  2. Which gives: 136 = 1 x
  3. Divide both sides by 1 to isolate x: 136 1 = 1 x 1
  4. Which gives the result: 136 1 = x

Thus, 2/1 of 68 is equal to 136/1 (or 136 in its decimal form).
