What is 7/1 of 58?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 7/1 of 58? We'll show you a straightforward method to achieve that.

How to calculate 7/1 of 58?

  1. Multiply the whole number by the numerator of the fraction: 58 × 7 = 406
  2. Divide this result by denominator of the fraction: 406/1 = 406

How does it work?

The principle behind finding a fraction of a number, such as 7/1 of 58, is rooted in the method of cross-multiplication.

Consider the following proportion: 7 1 = x 58 (where x represents 7/1 of 58)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 7 × 58 = 1 x
  2. Which gives: 406 = 1 x
  3. Divide both sides by 1 to isolate x: 406 1 = 1 x 1
  4. Which gives the result: 406 1 = x

Thus, 7/1 of 58 is equal to 406/1 (or 406 in its decimal form).
