What is x when 54 divided by x equals 81?

In other words, what would the divisor be if the dividend were 54 and the quotient 81?

To find the answer, just divide the dividend by the quotient: 54 ÷ 81 = 0.66666666666667

To prove this, let's compute 54 divided by 0.66666666666667: 54 0.66666666666667 = 81

How does it work?

Asking what the value of x could be when 54 divided by x gives a result of 81, is equivalent to solving the following equation:

54 x = 81

  1. Multiply both sides by x: 54 x x = 81 x
  2. 54 x x is equivalent to x x × 54 , which simplifies to 1 × 54 (or just 54 ).
  3. Thus, the equation becomes: 54 = 81 x
  4. To find x, divide both sides by 81: 54 81 = 81 x 81
  5. Which gives, after simplification: 0.66666666666667 = x (or x = 0.66666666666667 )

So, if the dividend is 54 and the quotient is 81, the divisor is 0.66666666666667.
