What is 10/2 of 67?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 10/2 of 67? We'll show you a straightforward method to achieve that.

How to calculate 10/2 of 67?

  1. Multiply the whole number by the numerator of the fraction: 67 × 10 = 670
  2. Divide this result by denominator of the fraction: 670/2 = 335
  3. Simplify by dividing both the numerator and denominator by their GCD (2):
    • 670/2 = 335
    • 2/2 = 1
  4. Which gives: 335/1

How does it work?

The principle behind finding a fraction of a number, such as 10/2 of 67, is rooted in the method of cross-multiplication.

Consider the following proportion: 10 2 = x 67 (where x represents 10/2 of 67)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 10 × 67 = 2 x
  2. Which gives: 670 = 2 x
  3. Divide both sides by 2 to isolate x: 670 2 = 2 x 2
  4. Which gives the result: 670 2 = x (or 335 1 = x )

Thus, 10/2 of 67 is equal to 335/1 (or 335 in its decimal form).
