What is x when 15 divided by x equals 57?

In other words, what would the divisor be if the dividend were 15 and the quotient 57?

To find the answer, just divide the dividend by the quotient: 15 ÷ 57 = 0.26315789473684

To prove this, let's compute 15 divided by 0.26315789473684: 15 0.26315789473684 = 57

How does it work?

Asking what the value of x could be when 15 divided by x gives a result of 57, is equivalent to solving the following equation:

15 x = 57

  1. Multiply both sides by x: 15 x x = 57 x
  2. 15 x x is equivalent to x x × 15 , which simplifies to 1 × 15 (or just 15 ).
  3. Thus, the equation becomes: 15 = 57 x
  4. To find x, divide both sides by 57: 15 57 = 57 x 57
  5. Which gives, after simplification: 0.26315789473684 = x (or x = 0.26315789473684 )

So, if the dividend is 15 and the quotient is 57, the divisor is 0.26315789473684.
