What is x when 83 divided by x equals 21?

In other words, what would the divisor be if the dividend were 83 and the quotient 21?

To find the answer, just divide the dividend by the quotient: 83 ÷ 21 = 3.952380952381

To prove this, let's compute 83 divided by 3.952380952381: 83 3.952380952381 = 21

How does it work?

Asking what the value of x could be when 83 divided by x gives a result of 21, is equivalent to solving the following equation:

83 x = 21

  1. Multiply both sides by x: 83 x x = 21 x
  2. 83 x x is equivalent to x x × 83 , which simplifies to 1 × 83 (or just 83 ).
  3. Thus, the equation becomes: 83 = 21 x
  4. To find x, divide both sides by 21: 83 21 = 21 x 21
  5. Which gives, after simplification: 3.952380952381 = x (or x = 3.952380952381 )

So, if the dividend is 83 and the quotient is 21, the divisor is 3.952380952381.
