What is 6/1 of 45?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 6/1 of 45? We'll show you a straightforward method to achieve that.

How to calculate 6/1 of 45?

  1. Multiply the whole number by the numerator of the fraction: 45 × 6 = 270
  2. Divide this result by denominator of the fraction: 270/1 = 270

How does it work?

The principle behind finding a fraction of a number, such as 6/1 of 45, is rooted in the method of cross-multiplication.

Consider the following proportion: 6 1 = x 45 (where x represents 6/1 of 45)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 6 × 45 = 1 x
  2. Which gives: 270 = 1 x
  3. Divide both sides by 1 to isolate x: 270 1 = 1 x 1
  4. Which gives the result: 270 1 = x

Thus, 6/1 of 45 is equal to 270/1 (or 270 in its decimal form).
