What is 8/8 of 79?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 8/8 of 79? We'll show you a straightforward method to achieve that.

How to calculate 8/8 of 79?

  1. Multiply the whole number by the numerator of the fraction: 79 × 8 = 632
  2. Divide this result by denominator of the fraction: 632/8 = 79
  3. Simplify by dividing both the numerator and denominator by their GCD (8):
    • 632/8 = 79
    • 8/8 = 1
  4. Which gives: 79/1

How does it work?

The principle behind finding a fraction of a number, such as 8/8 of 79, is rooted in the method of cross-multiplication.

Consider the following proportion: 8 8 = x 79 (where x represents 8/8 of 79)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 8 × 79 = 8 x
  2. Which gives: 632 = 8 x
  3. Divide both sides by 8 to isolate x: 632 8 = 8 x 8
  4. Which gives the result: 632 8 = x (or 79 1 = x )

Thus, 8/8 of 79 is equal to 79/1 (or 79 in its decimal form).
