What is x when 65 divided by x equals 81?

In other words, what would the divisor be if the dividend were 65 and the quotient 81?

To find the answer, just divide the dividend by the quotient: 65 ÷ 81 = 0.80246913580247

To prove this, let's compute 65 divided by 0.80246913580247: 65 0.80246913580247 = 81

How does it work?

Asking what the value of x could be when 65 divided by x gives a result of 81, is equivalent to solving the following equation:

65 x = 81

  1. Multiply both sides by x: 65 x x = 81 x
  2. 65 x x is equivalent to x x × 65 , which simplifies to 1 × 65 (or just 65 ).
  3. Thus, the equation becomes: 65 = 81 x
  4. To find x, divide both sides by 81: 65 81 = 81 x 81
  5. Which gives, after simplification: 0.80246913580247 = x (or x = 0.80246913580247 )

So, if the dividend is 65 and the quotient is 81, the divisor is 0.80246913580247.
