What is 6/1 of 42?

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 42? We'll show you a straightforward method to achieve that.

How to calculate 6/1 of 42?

  1. Multiply the whole number by the numerator of the fraction: 42 × 6 = 252
  2. Divide this result by denominator of the fraction: 252/1 = 252

How does it work?

The principle behind finding a fraction of a number, such as 6/1 of 42, is rooted in the method of cross-multiplication.

Consider the following proportion: 6 1 = x 42 (where x represents 6/1 of 42)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 6 × 42 = 1 x
  2. Which gives: 252 = 1 x
  3. Divide both sides by 1 to isolate x: 252 1 = 1 x 1
  4. Which gives the result: 252 1 = x

Thus, 6/1 of 42 is equal to 252/1 (or 252 in its decimal form).
