What is x when 91 divided by x equals 15?

In other words, what would the divisor be if the dividend were 91 and the quotient 15?

To find the answer, just divide the dividend by the quotient: 91 ÷ 15 = 6.0666666666667

To prove this, let's compute 91 divided by 6.0666666666667: 91 6.0666666666667 = 15

How does it work?

Asking what the value of x could be when 91 divided by x gives a result of 15, is equivalent to solving the following equation:

91 x = 15

  1. Multiply both sides by x: 91 x x = 15 x
  2. 91 x x is equivalent to x x × 91 , which simplifies to 1 × 91 (or just 91 ).
  3. Thus, the equation becomes: 91 = 15 x
  4. To find x, divide both sides by 15: 91 15 = 15 x 15
  5. Which gives, after simplification: 6.0666666666667 = x (or x = 6.0666666666667 )

So, if the dividend is 91 and the quotient is 15, the divisor is 6.0666666666667.
