What is x when 57 divided by x equals 90?

In other words, what would the divisor be if the dividend were 57 and the quotient 90?

To find the answer, just divide the dividend by the quotient: 57 ÷ 90 = 0.63333333333333

To prove this, let's compute 57 divided by 0.63333333333333: 57 0.63333333333333 = 90

How does it work?

Asking what the value of x could be when 57 divided by x gives a result of 90, is equivalent to solving the following equation:

57 x = 90

  1. Multiply both sides by x: 57 x x = 90 x
  2. 57 x x is equivalent to x x × 57 , which simplifies to 1 × 57 (or just 57 ).
  3. Thus, the equation becomes: 57 = 90 x
  4. To find x, divide both sides by 90: 57 90 = 90 x 90
  5. Which gives, after simplification: 0.63333333333333 = x (or x = 0.63333333333333 )

So, if the dividend is 57 and the quotient is 90, the divisor is 0.63333333333333.
