What is x when 87 divided by x equals 91?

In other words, what would the divisor be if the dividend were 87 and the quotient 91?

To find the answer, just divide the dividend by the quotient: 87 ÷ 91 = 0.95604395604396

To prove this, let's compute 87 divided by 0.95604395604396: 87 0.95604395604396 = 91

How does it work?

Asking what the value of x could be when 87 divided by x gives a result of 91, is equivalent to solving the following equation:

87 x = 91

  1. Multiply both sides by x: 87 x x = 91 x
  2. 87 x x is equivalent to x x × 87 , which simplifies to 1 × 87 (or just 87 ).
  3. Thus, the equation becomes: 87 = 91 x
  4. To find x, divide both sides by 91: 87 91 = 91 x 91
  5. Which gives, after simplification: 0.95604395604396 = x (or x = 0.95604395604396 )

So, if the dividend is 87 and the quotient is 91, the divisor is 0.95604395604396.
