What is x when 20 divided by x equals 21?

In other words, what would the divisor be if the dividend were 20 and the quotient 21?

To find the answer, just divide the dividend by the quotient: 20 ÷ 21 = 0.95238095238095

To prove this, let's compute 20 divided by 0.95238095238095: 20 0.95238095238095 = 21

How does it work?

Asking what the value of x could be when 20 divided by x gives a result of 21, is equivalent to solving the following equation:

20 x = 21

  1. Multiply both sides by x: 20 x x = 21 x
  2. 20 x x is equivalent to x x × 20 , which simplifies to 1 × 20 (or just 20 ).
  3. Thus, the equation becomes: 20 = 21 x
  4. To find x, divide both sides by 21: 20 21 = 21 x 21
  5. Which gives, after simplification: 0.95238095238095 = x (or x = 0.95238095238095 )

So, if the dividend is 20 and the quotient is 21, the divisor is 0.95238095238095.
