What is 3/3 of 69?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 3/3 of 69? We'll show you a straightforward method to achieve that.

How to calculate 3/3 of 69?

  1. Multiply the whole number by the numerator of the fraction: 69 × 3 = 207
  2. Divide this result by denominator of the fraction: 207/3 = 69
  3. Simplify by dividing both the numerator and denominator by their GCD (3):
    • 207/3 = 69
    • 3/3 = 1
  4. Which gives: 69/1

How does it work?

The principle behind finding a fraction of a number, such as 3/3 of 69, is rooted in the method of cross-multiplication.

Consider the following proportion: 3 3 = x 69 (where x represents 3/3 of 69)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 3 × 69 = 3 x
  2. Which gives: 207 = 3 x
  3. Divide both sides by 3 to isolate x: 207 3 = 3 x 3
  4. Which gives the result: 207 3 = x (or 69 1 = x )

Thus, 3/3 of 69 is equal to 69/1 (or 69 in its decimal form).
