What is 3/6 of 33?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 3/6 of 33? We'll show you a straightforward method to achieve that.

How to calculate 3/6 of 33?

  1. Multiply the whole number by the numerator of the fraction: 33 × 3 = 99
  2. Divide this result by denominator of the fraction: 99/6 = 16.5
  3. Simplify by dividing both the numerator and denominator by their GCD (3):
    • 99/3 = 33
    • 6/3 = 2
  4. Which gives: 33/2

Since 33/2 is an improper fraction, the result could also be expressed as a mixed number: 16 1/2

How does it work?

The principle behind finding a fraction of a number, such as 3/6 of 33, is rooted in the method of cross-multiplication.

Consider the following proportion: 3 6 = x 33 (where x represents 3/6 of 33)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 3 × 33 = 6 x
  2. Which gives: 99 = 6 x
  3. Divide both sides by 6 to isolate x: 99 6 = 6 x 6
  4. Which gives the result: 99 6 = x (or 33 2 = x )

Thus, 3/6 of 33 is equal to 33/2 (or 16.5 in its decimal form).
