What is 7/2 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 7/2 of 69? We'll show you a straightforward method to achieve that.

How to calculate 7/2 of 69?

  1. Multiply the whole number by the numerator of the fraction: 69 × 7 = 483
  2. Divide this result by denominator of the fraction: 483/2 = 241.5

Since 483/2 is an improper fraction, the result could also be expressed as a mixed number: 241 1/2

How does it work?

The principle behind finding a fraction of a number, such as 7/2 of 69, is rooted in the method of cross-multiplication.

Consider the following proportion: 7 2 = x 69 (where x represents 7/2 of 69)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 7 × 69 = 2 x
  2. Which gives: 483 = 2 x
  3. Divide both sides by 2 to isolate x: 483 2 = 2 x 2
  4. Which gives the result: 483 2 = x

Thus, 7/2 of 69 is equal to 483/2 (or 241.5 in its decimal form).
