What is 8/2 of 76?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 8/2 of 76? We'll show you a straightforward method to achieve that.

How to calculate 8/2 of 76?

  1. Multiply the whole number by the numerator of the fraction: 76 × 8 = 608
  2. Divide this result by denominator of the fraction: 608/2 = 304
  3. Simplify by dividing both the numerator and denominator by their GCD (2):
    • 608/2 = 304
    • 2/2 = 1
  4. Which gives: 304/1

How does it work?

The principle behind finding a fraction of a number, such as 8/2 of 76, is rooted in the method of cross-multiplication.

Consider the following proportion: 8 2 = x 76 (where x represents 8/2 of 76)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 8 × 76 = 2 x
  2. Which gives: 608 = 2 x
  3. Divide both sides by 2 to isolate x: 608 2 = 2 x 2
  4. Which gives the result: 608 2 = x (or 304 1 = x )

Thus, 8/2 of 76 is equal to 304/1 (or 304 in its decimal form).
